i certainly hope that tetris party deluxe game is a somewhat neutral tetris game.
most recent tetris game i could find which interested me was tetris DX(GBC)
tetris on the GBA: either japanese menu's(couldn't find where the BGM select was) or too much animation in the background
tetris DS: nintendo characters all over the screen distracting me, and no ability to just have it play the classic tetris theme on the background
tetris PSP(mini by EA): best one, except the horrible "remix" of the tetris theme(tetris theme playing on some low volume, with drums and stuff going through it at high volume)
so i hope this one has: no characters going through the actual play area, and the original or a decently remixed tetris theme.
oh, and here's hoping we can get .bdx files working with jam with the band.
