Tunic - at face value it is a gorgeous, brilliantly fun soulslike. Beneath the surface, however, it becomes apparent that the "souls like" part of it is a facade for the true game. Probably one of the single greatest gaming experiences of all time.
The Witcher 3 - it often goes on sale for like... £3 or something ridiculous, and its a standout example of an excellent open world RPG.
Celeste - possibly the single greatest (2d) platforming game ever made, with a soundtrack that is truly unforgettable by the great Lena Raine. Also if you play it you'll find out you're trans*
Yeah I adore Outer Wilds and I think the storytelling experience of it is gorgeous - one of my all time favourites. I settled on not mentioning it here because I think its a tad less accessible due to the ship movement.
Done Celeste... Well... Still playing. Done A-B-C sides. Now I'm onto the D sides which are fan made. Way harder but it's really well made. Feel official. There's also the Stawberry Jam mod which offer like a full game worth of content. Didn't play that much yet.
Its in my highest ranked game. It's up there with a very few masterpieces. Like top 5 ish ever. I don't think it's for everybody but goddamn this game is something.
I loved strawberry jam, what a monumental fan work.
I think Celeste can be for everybody, with assist mode you can tune the difficulty to your liking if you're a less experienced gamer, and the game encourages you the whole way through a well balanced difficulty curve (IMO).
