Hate to say this, but the rest of the world says that tetris is the best puzzle game ever. Sales, Web Hits, whatever statistic you want to whip out will prove it. MAYBE puyo puyo (its been around just as long) would win in Asia, but as far as puzzle games go, more people like Tetris than any otehr puzzle game. (even if you say you know more people who hate tetris - you are not the center of the world)
Tetris Advance (J) is great! Someone should fix this games for Emulators and Pogoshell. Maybe its a new save mode?
