DoomRL is considerably harder than the original. Random levels, so no picking your favorite zombie or barrel to shoot at the start of Phobos Anomaly even though they'll blow themselves up if you just stand there(and wave). Most of the enemies in DoomRL move significantly faster than the originals, roughly at the original Doomguy's sprint speed, it seems. Speaking of which, yeah. Alpha Doomguy could run forever, no fatigue for him. I had Doom for the PlayStation, so i never met a [size=32Vpt][/size] back then, i dunno how they compare. No strafe in the RL; shottyman is the closest thing. Alpha Cybie was a joke compared to his RL counterpart, as were mancubi, barons, arachnotrons, revenants, knights, cacodemons, and just about everything else. Demons, lost souls, and former humans are about par, though. Boosted health didn't decay in the original. Enemies couldn't use items, though they never ran out of ammo(boo hoo).
I was really good at Doom. After i cleared a level, i went around and collected goodies so i could start the next at 200%/200% with full ammo and glowing eyes of god. Not only that, but i LEFT powerups behind for the next marine who wandered through hell; this gesture felt and still feels important to me, so i still economize like a man obsessed in DoomRL. I would seek out the smaller ammo packs, leaving the boxes for the next guy. I would skip armor shards and blue bottles unless i desperately needed them, going so far as to TIPTOE AROUND THEM. (i could afford to do all this because PS1 Doom didn't have N! >_<)
DoomRL is different. No dancing around Cybie, humming a sprightly tune as you fire rocket after rocket at his crotch(that's where the rockets connected, it was awesome). Try taking on The Wall with green armor and a double shotgun; fifteen Barons were lunch for a character equipped thus in the original. In DoomRL, by the time ONE Baron isn't a significant threat to your character, he'll have brought his two brothers, his nephews, and his pet spider.
In the original Doom, you had to pull levers and flip switches; the worst that could happen was releasing a manageable number of enemies, as spawn levers in DoomRL do. Levers didn't punish you with death for your curiosity.
I could probably go on, except i've already bored myself. And since the thread got locked (and was, in fact, the main reason i joined the forum at all *grr*), my favorite level is Sever the Wicked, i think it was playstation exclusive. Easiest of the final Ultimate Doom levels, but still completely frantic.
