The trackball would make it amazing. I would absolutely buy this game if it came out for blackberries with trackball support.

That would seem to be a pretty hardware intensive game.

I wonder if the Pearl could handle something like that?

Well, I meant a scaled down version of it. it might still be pretty intensive to have a simulated 3d environment, but it wouldn't be that much more intense than a copy of monkey ball I had on a phone of mine years ago.

edit: also, they are coming out with a phone version of katamari in japan, and it will use the camera and tilting to sense which direction you want it to move in. Im not sure how great that will be.
