Very few games get the chance to have this many variations, but that's just a testament to how darned good TETRIS was to begin with. Well, now it's back, and it's brought a few new ideas (as well as all of the old ones) to the PlayStation 2. Each version of the game takes place on a different planet, giving TETRIS a chance to showcase some cool graphics for a change. As always, the game challenges you to arrange falling blocks into perfect lines, creating more space with which to stack up more pieces… But, you already know that.
