A grand old time; the first FPS I've ever played where I actually enjoyed the combat. Not a big fan of the "key hunting" aspect, which feels retrograde more than it feels properly "retro" (I applaud people who can find the fun in wandering through empty environments to look for a corpse they missed), but I was very pleased to discover that the second half of the game has almost none of that! Two of the three boss fights are also a bit underwhelming, but the good one is reeeeeeeally good, so y'know, it's all fine with me. These are all nitpicks, anyway. DOOM's good aspects are all but self-evident. Explaining why this game is fun would be like explaining the appeal of the whole medium.
