There is absolutely nothing wrong with this game. It should go down as the greatest game in history. Despite it being graphically challenged, it is flawless. It has perhaps the greatest story in all of gaming, and is without a doubt the funnest. The game is spread out into three different episodes, and in the computer version, there is a fourth called, Thy Flesh Consumed. No reason not to buy this game, you should be able to buy it at Wal-Mart or Best Buy, in like a collectors edition containing Doom 2 and Final Doom as well, it was about $10. You can also buy it if you buy the collectors edition of Doom 3, it is in the extras menu and also comes with Doom 2. BUY THIS GAME!
