I think there's no such a thing as a perfect game. Every game has its faults, but the best ones manage to make us look past them. However, sometimes a game manages to do something so well, so spectaculary, that I think the entire industry should recognize it for that.
For me one of those games was Bioshock: Infinite.
What about you? Do you have a game in your mind that you think has done something so perfectly that you wish other games would follow in its footsteps?
