While I am certainly a fan of a pretty game, visuals are by no means the only standard that I judge a game's quality on. One of my all-time favorite games is a permadeath bullet-hell game called Realm of the Mad God, a game that is mostly populated visually with 8x8 sprites. It's not an ugly game by any measure, but the focus is clearly not on utilizing current-gen hardware.
I'm curious what you all have in mind!
