How about this, an FPS without combat, a puzzle game with amazing npcs, a platformer with an astounding story, this is Portal 2.
It's crazy how good everything this game does is just perfect, it's the best puzzle game ever , it's chalenges are so well-tought and the level design makes you fell like a genius when you solve stuff, but really the genius were those who made this.
Truly and all around masterpiece, and one of , if not the, my favorite games, the only problem is that i still don't have a cake :(
