Hogwarts Legacy.
I used to be a big Harry Potter fan but stopped liking them back in my teens after the fifth book and only read the last two to finish the series. So while I was interested in the sound of the game I didn't expect to be overawed by it.
Boy, was I wrong. I. Am. LOVING. It.
It's set in the 1800s (and because wizards are basically stuck in that asethetic anyway, you barely even notice this) so the only thing from Potterworld is the setting itself (and a few familiar names, because the Wizarding world is so small and interbred), with its own unique storyline. I didn't expect to be so involved in that but the game starts in a seriously dramatic way that does get you invested.
But the thing I can't get over is how BIG the game is. Of course you expect Hogwarts, and it's a full sized Hogwarts with all the random corridors, stairs, rooms, puzzles, ghosts, moving portraits and whatnot. But then you also have Hogsmeade, which is a large village full of houses and shops. But then you also have a huge section of the Scottish Highlands full of hamlets, puzzles, dungeons, creatures, and roving enemies. It's MASSIVE.
I think it's important to note that it's not The Sims: Hogwarts. You don't need to go to bed on time (or at all), while students chat among themselves you can't interact with them unless the game allows, you don't have to go to classes unless it's important to the story, you can't sit down to meals with your House friends. What it more is is Elder Scrolls: Hogwarts. I've been disappearing (and making a joke about it, in that teachers must be thinking 'we haven't seen the new student for three weeks...') into the Highlands to explore at all opportunities, but like with Skyrim it seems likely that the main quest will take you to most spots and encourage you to stay a while and do all the things available in the area.
The combat is great, fluid but also packs a punch so you actually feel deadly. It's a weird mix of being very simple with not that many spells to learn, but also tricky in that you can switch spell slots while in combat and also toss in things like deadly plants and useful potions.
It's a really beautiful looking game as well.
Overall, I'm so glad I bought it. Of course it's going to appeal to Harry Potter fans (lots of set pieces to come across, like Peeves scaring the crap out of students, enchanted armour, students messing around with magic etc) but I think it's also well worth the look from people who enjoy open world RPGs in general because as I say it's not that much Harry Potter at all.
Highly recommend.
