I know, I just COULDN'T have one poll. WHich is the better tilt-sensing game: Loco Roco for PSP or Yoshi Topsy-Turvy for GBA? MY vote goes to Loco Roco, although YTT has a better storyline and graphics.
Loco Roco is a cute little PSP game where you role this little yellow jelly blob around. As far as I know, the rolling mechanism is the key part of the game: even just moving requires it. Yoshi Topsy-Turvy? I wrote all about it on our Mariowiki, so read up ^_^
