I've never played any game like this. The physics are awesome -- you're out in space and pretty much every piece of rock has earth normal gravity of it's own. The playability is awesome too with the great use of the wii controls.
But what pushed it over the top for me is that fact that I can play it with Gabe. He can use his own controller, point it at the screen to pick up power-ups or grab enemies to hold them. So we play the game together, which is so cool. Great game!
