which is not technically a full game but I'm counting it anyway. If you played or like Undertale but haven't been pulled in by Deltarune, then I get you, I was there too. Chapter 1 seemed fine, a nice start but nowhere near the heights of Undertale, and I watched it on YouTube once and never came back to it. But then when Chapter 2 came out, I decided to download and play the two chapters. And yeah, Chapter 1 is nice, its fun and cute, its got great music, but there's nothing particularly touching imo. But Chapter 2 is imo the best writing Toby Fox has done, even better than Undertale. Obviously its not a full story, so there's a lot more to be seen, but its consistently amazing. The main villain, Queen, is hilarious, one of my favourite characters. Berdly is a gamer. Noelle is gay. Spamton is quite insane. The characters are just absolutely brilliant and captivating. It examines the relationship between the player and the main character, Kris, and how you basically hijack their life to play the game. Kris gets loads of characterisation in Chapter 2 despite being a stone-faced silent protagonist. Kris has interests, they're mischievous, they miss their brother, they play the piano, and you take all that away from them when you play the game.
Also Kris is the only non-binary main character in gaming I've ever seen, so thanks Toby. Deltarune is amazing.
