@pmanden: I agree. I think games from that era tend to age the best. Yoshi's Island is a perfect example of a game that is visually timeless. A lot of games these days are doomed to age poorly especially those that aim to look realistic as they will lose there graphical appeal as graphics continue to look more advanced and realistic, while a lot of SNES, Genesis, and even NES games will remain to look classy.
And yeah a lot of indie games try to imitate the oldschool look and feel exactly like that. Imitation instead of authentic and not to say they look bad but in a way awkward imo.
