A few of the games released on the console also saw releases on the handheld. I was fortunate enough to FINALLY run across a copy of Chu Chu Rocket for the GBA and I'm amazed at how fun this is on the GBA!
Does anyone have Jet Grind Radio for the GBA and if so, how did that one turn out? Probably not nearly as good as this one, but...what the hell...I might pick it up anyway.
