I just got an e-mail from Nintendo saying that it will have a tilt sensor built into the game pack and that you have to tilt your GBA to make Yoshi roll on a ball and stuff. Sounds fun! :D
I've never heard of renting Gameboy Advance games. :P I think they might be a bit small for that. Anyway, we'll just have to wait and see for when it's released, because I would certainly like to try it.
Hahaha, I can imagine this game on the Gameboy Player for the Gamecube. People picking up their Gamecubes and swinging them around. Others would think they were dancing with it or just plain crazy. :D
