Hyper Light Drifter looks pretty rad, and part of that is due to the cool looking 2D style. Recently developer Alex Preston responded to a question regarding a 1080p resolution for the game, and had this to say, "Our game is 480p. It’s low resolution, and very intentionally so. It is pixel style, so why would we make it 1080p? I don’t think anybody actually cares about this with 2D games. It’s always more of a question of 3D games. Resolution actually matters in that case. But in 2D games, it’s just the resolution you draw your sprite at. I don’t think that question has ever been a point of interest for anybody on 2D games, really."
I think a lot of people do care, but in my personal view, he's right. I don't really care so much about visuals for games like this so long as the framerate is steady and the style is interesting.
