Possibly the best game ever made. Decidedly not my genre in multiple ways and still it just does so many things so right it is hard not to be totally astounded by it.
When the 360 was extremely light on releases, it had Gun. This is a super mediocre game that came out at just the right time for me to spend hours playing it,
Best roguelike ever made. Supergiant is possibly the single best indie game studio of all time. Everything they make is a masterpiece. This game is the masterpiece of masterpieces.
