Sometimes, you really want to like a game, but it does everything in its power to keep that from happening. Case in point: Doom, a game released on about a million systems, arrived on two different Sega consoles in as many years. The problem is that both of them were well... less than what was expected. In fact, we don't know which one is worse, so we shackled staff writer Nick Gibson to a desk and made him play them both extensively. After much suffering and even more caffeine, he's given us his results. Read our Side by Side comparison and see which Doom is the less potent of two poisons.
