Ask just about anyone who is or was an avid Panel de pon gamer and they'll tell you that (most often prevalent at the beginning of the period they first became serious about the game) they even unwillingly dreamed about block configurations, chain reactions, etc. regarding this game. It affects the mind in a way that few games can.
Panel de pon existed before Tetris attack, and Pokemon Puzzle league for the Nintendo 64 took the difficulty to new levels with improved A.I. While "Planet Puzzle League" for the DS now gives us online play. But for many, Tetris attack, because of the music, or the familiar characters, the nostalgia, or whatever personal reasons people may have makes it the most beloved version of the game.
