Tetris Worlds (Game Cube, 2002)

This game is wonderful because it has all of the elements of the old school Tetris, but it also has new elements that liven it up a bit. You also get to choose different gaming styles which is very cool and only adds to the fun. Nintendo did everything right with this one. They kept enough of the tried and true old school element of Tetris that everyone originally fell in love with, but also added enough new twists to the game so that it doesn't get boring. You can literally play this game for hours on end without getting bored. I highly recommend it to anyone who is thinking about getting it.
