This really does not need further discussion. If you are not already downloading Audiosurf, you should be going to do so now. The game is simple, it is good, it includes the Orange Box soundtrack, and it's a 10-dollar title that will outlast many 50-dollar games. No more words are necessary; only action is needed. If you are not convinced, watch a few videos. There are top-quality games the reviewer has played before and would not recommend to all players. Audiosurf is a top-quality game he recommends to absolutely everyone.
