Yes, I finally played this landmark game just a few years ago. I toyed with the sequel "Doom II" in high school and came away unimpressed, but the predecessor is far superior. There's a reason this is the FPS big daddy, and it isn't because of its shocking content. Unlike Mortal Kombat, the gore in Doom is secondary to the game design. Even with a limited texture set, the levels are memorable via spatial variety. Each foe has a distinct behavior and audio cue. And when you grab a key only to hear a trap door slide open behind you, it's a thrill to survive the literal “all hell breaks loose.”
