I came late to the Doom party. I only picked up a copy of The Ultimate Doom for Windows 95 earlier this year (made it work on my old XP with SkullTag), and I was in awe. This is the kind of shooter I like. No cover, no regenerating health, none of that plaguing garglemesh that lags the experience behind! Gotta love its history, its uniqueness, and its unrelenting onslaught!
