Dragon age inquisition is quite similar from an exploration and combat perspective.

Maybe Lego City Undercover, My Time in Portia, Red Dead Redemption, Assassin’s Creed Origins, or Immortals Fenyx Rising.

Gta

I mean, Witcher 3 and Skyrim have an insane amount of content, but are more RPG than action adventure and may feel slow after coming from Hogwarts. But both have standard combat and magic. Worth a try if you haven't played them.

Control is a great game with a good main story, great side quests, and a bunch of collectables. It's a third person shooter with super powers. Only problem it's not what I would consider open world in the same sense as Hogwarts.

Any of the Assassins Creed or Tomb Raider games match the feel of open world compared to Hogwarts and are full of content, but lack the magical component.

Also the two Star Wars Jedi games would be a good try as well.

This game feels like Assassins Creed: Hogwarts in alot of ways; maybe she'd enjoy the "RPG" trilogy?

Dragon age games are all good and with magic theme.

I love Dragon Age Inquisition.

AC: Odyssey, is a good one

Just play Skyrim again lol

I am relatively new to gaming too, got absolutely hooked by Red Dead Redemption 2

I posted similar in another comment but I LOVED Assassin's Creed Odyssey, it was the next game I played after Hogwarts Legacy. I was new to gaming and literally bought my console cos of HL. I didn't get on with AC Origins personally but I can see the appeal of the game, I just didn't get into it properly but I probably will go back to it for another go soon.

I also played the Lego Harry Potter games and enjoyed them. They're not really open world with a map or anything but it kind of leads you through the story then you get free rein.

I also enjoyed the original Tomb Raider game remasters but dunno how much of that was nostalgia cos I played tomb raider 1 as a kid on PC and could never get very far so felt very successful for managing it now in my 30's 🤣

Assassins Creed Origins! It’s got constellations, a good storyline, huge map, and tons of side quests, etc. You can also change your appearance of your items like in legacy and there’s multiple mounts. There’s also downloadable content as well.

I very much second the recommendations for Breath of the Wild and Tears of the Kingdom. They fit most of what you are looking for really well. The story isn’t exactly linear, but it also doesn’t matter what order you do things or affect the ending in any way.

I really like Legend of Zelda, it’s open world, graphics are great. The puzzles can be a little challenging. There is fighting but it’s pretty comparable to HL. I honestly wish it was available on the PS5.

Same for me, I just like the mini games and swinging through New York. I even dreamed I was swinging haha

Assessins creed origins & all the Spider-Man games. The Spider-Man games are similar to Hogwarts legacy imo

Lego Harry Potter? It’s not exactly the same, but it’s still a Harry Potter game. 

May I suggest the Witcher? It seems very overwhelming at first, but playing it on easy mode helps (and I didn’t even bother learning much alchemy) or even Skyrim, and using a mage build could somewhat resemble being a wizard/witch!

Horizon: Zero Dawn & Horizon: Forbidden West

Greedfall

Assassins Creed RPGs: Origins, Odyssey & Valhalla

Ghost of Tsushima

EDIT: Took off Witcher 3 and Skyrim, they may be a bit overwhelming for OP.

Personally I went straight into breath of the wild. Had a guided story just likeHL

Horizon zero Dawn, definitely

Tru Damon x machina not like it but the action gameplay are unique in a hogarth way

Action RPG. Final Fantasy Crisis Core, Y’s 8-10, Kingdoms of Amalur, and Star Ocean: The Second Story. Haven’t played Kingdom Come Deliverance or Nier. Good luck.

Sounds like a Ubisoft game might be up your alley. One of the Assassin’s Creed games might be to your liking. Origins covers ancient Egypt, Odyssey covers the Greek era, and Valhalla has Vikings.

Or Immortals Fenyx Rising if you want something a bit lighter in tone.

Ubisoft games are generally pretty guided and checkmarky. You open your very large map and it’s filled with icons marked with everything the game has for you, which seems to be what you’re looking for.

The Witcher 3 and Skyrim are both games that feature a nice main story, with especially the Witcher 3 also featuring lots of interesting side quests. Both games are also much better in the action RPG department as Hogwarts Legacy, especially when it comes to collecting gears & items, leveling, and exploring interesting locations in the open world. As to the fighting: though not the main focus like in Hogwarts Legacy, both games feature extensive use of magic. Other games down this lane are the Fable games and Skyrim's predecessor Oblivion, though Oblivion is a pretty old game and both don't come anywhere near the modern graphics in Hogwarts Legacy (though admittedly graphics in Skyrim, unless running mods on PC, also don't hold up compared to more recent games). Besides the Elder Scrolls series, the Fallout series offers a similar experience (except Fallout 76), though without the magic and instead of a thriving fantasy world a rather depressing wasteland. It also offers a morality system in a few of the games like Fallout 3, in Fallout 4 there is still some focus on the morality of actions but there isn't any morality system. Other games that offer a good story with compelling narrative: Plague Tale (medieval|linear|little combat), Guardians Of The Galaxy (crazy fantasy environments|focus on dialogue|linear), Persona 5 (JRPG|90+ hours, which might get a slog towards end|jumps between life simulator in day time, and getting into turn-based combat action after school), ...These are all great games, but have less in common with Hogwarts Legacy

If you enjoyed the large world with all the objectives scattered around, you might also like Ubisoft games (as suggested by u/GuessWh0m). Though these games have less compelling main stories, and can be a bit bloated with random objectives (especially Valhalla had this problem, while I thought Assasin's Creed Odyssey was a better game with a more compelling main story). Anyway, if you're okay with that they offer a ton of content and a beautiful world to explore. Immortals Fenyx Rising is a Ubisoft game that offers a more unique experience compared to the long running series of Far Cry and Assasin's Creed that all feel pretty similar, it also holds your hand less than some other Ubisoft titles. It even has, similar to Hogwarts Legacy, a collectible that can only be accessed at night, though that makes up one of the few irritating quirks of the game.
;-)
Watch Dogs 2 is another Ubisoft game (think Ubisoft's GTA with hacking), it offered a vastly improved gameplay over the original and offered a pretty decent story. There are still many random objectives, but there is some variety and it feels like a more unique & cohesive experience. The open world is really beautifully crafted and is actually really populated, though repetitive activities might get boring as you play the game longer. There are also some worthwhile side missions, though it doesn't go very deep into that. In addition there are pretty okay online activities with for instance some friends. It also goes further as Hogwarts Legacy when it comes to choosing between the good and bad guy option: you can either choose to complete missions non-lethally or go in and kill everyone. There are however some parts that make messing around in the game a bit less fun, like subpar driving mechanics and pretty lackluster gunplay.

When it comes to adaptations of magical universes, similar to how Hogwarts Legacy is in largely adapted from the existing lore in the Harry potter books, you might also enjoy Middle Earth: Shadow of War, the Witcher 3, or the more compact Bioshock which delivers great first-person shooters within a unique setting.

In case the immersion of Hogwarts Legacy was something you thoroughly enjoyed, on that front Red Dead Redemption 2 offers perhaps the best experience in the gaming industry (with a mix of cozy activities and fighting, and some consequences to your kind deeds or hideous crimes). Admittedly the world isn't set in the Wizarding World, but while the wild west can be brutal the world offers a lot of 'magical' moments. The main story is also extremely compelling in my opinion, and instead of the random main character in Hogwarts Legacy it really immerses you in someone's story that feels really authentic: more like the wild ride of Harry Potter's unique storyline, that offered all the crazy twists but also lots of personal experiences. However, most of your time will probably be spent just immersing yourself in the vast open world, with all its unique encounters and areas to discover.

If you really liked the idea of making different decisions in Hogwarts Legacy, but wanted the decisions to have an actual impact you will certainty enjoy the Mass Effect Legendary Edition. The first entry in this trilogy hasn't aged that well (it's still the 2007 version, but with a new coat of paint), but the full remastered package still remains an excellent gaming experience. It are great RPGs, which are pretty unique by offering a more linear & very story driven experience. Combined with the choices you can make this results in a very immersive experience.

Random extra recommendation: if you would have liked deeper gameplay around capturing fantastic beasts, Monster Hunter revolves entirely around this prospect. It also offers an interesting world and has some cozy game elements, though it's notably weaker when it comes to main story and mostly focuses on just endlessly hunting creatures and upgrading and preparing for the next hunt at your base of operations: providing a gameplay loop that is best experienced with friends. Could for instance also be an interesting franchise to try out if you played through Witcher 3 and really liked the missions where you had to hunt beasts, though it are two vastly different games.

I admit I had some trouble while getting used to the controls but I think Red Dead Redemption 2 fits your needs.

Another shout for Immortals Fenyx Rising.

Immortals Fenyx rising is the correct answer.

I've heard Witcher 3 is similar.

The assasins creed rpg games. Origins, odyssey, valhalla and mirage. And ghost of tsushima (made by the same developers as assasins creed)

They all have very similar game play, map, things to do etc.

#SKYRIM

Baldurs gate is fantastic for that "list of things to do" type of game. Running around. You can play as a wizard so you get a ton of spells. And it's turn based so it's not intense when youre in a fight, you can take your time and choose the right spell and choose where you want to stand. It's so much fun. Ive played through 4 times, on my 5th now and there's still new stuff I havent seen.

Skyrim and now Oblivion Remastered are the main titles I otherwise play.

What aspects of the game do you enjoy the most? That will help with recommendations. Is it side quests? Combat? Open world?

Avatar Frontiers of Pandora is really cool and you can play this one solo or cooperatively all the way through. It is not exactly the same as HL but it is even more beautiful. It kinda reminded me a bit of like HZD meets Far Cry.

I’d recommend Ghost of Tsushima

Skyrim

The recent Assassins Creed games. The mechanics are almost identical. Combat is the same, down to having different “wheels”of spells/skills. Exploration is the same (chests, side quests etc). Even the petrificus totalus is the same as assassinations in AC. Huge maps with lots to do. It’s so similar I was shocked when I played HL. I would recommend AC Odyssey (ancient greece) and AC Valhalla (vikings). AC Mirage (middle east) was good too but much smaller. AC Shadows (Japan) comes out in march

It's hard to say without more info but if you don't mind a zombie apocalyptic setting, The Last of Us (I and II) could be good. Only if you have a Play Station tho.

If you say what consoles do you have, what genres are you into and how much do you value the gameplay (specially in terms of complexity/difficulty), people would be able to make better recomendations.

Red Dead Redemption 2 is an excellent game that you may love. It's an open world Western with a great story and memorable characters

Beginner friendly and tons of fun 🤙

It's nice to get locked into a game and feel the story. I have been feeling this with Cyberpunk 2077: Phantom Liberty. Not the same style game at all but it's been a lot of fun.

Hogwarts is pretty unique setting. But if you wanna run around a mage/wizard again maybe try out the tride and true Skyrim. You can create your character head to toe. Its completely open world. hundreds or quests and items to get.

​

Hogwarts in terms of gaming mechanics didn't do anything crazy new, but the world, characters, and story are all pretty unique that'll will make it hard for you to find something comparable

The uncharted games feel like you’re playing through an action/adventure film a la Indiana Jones.
