Me too. In the early 90s we'd stay after work and load Doom II on the machines to do network deathmatch past midnight with custom-made maps. Our sadist in-house author put the BFG on a tower in a courtyard so you'd have to run through a shooting gallery to get to it. But there's still nothing like sneaking up behind someone with the DB, shooting him point-blank, and hearing "DAMNIT, YOU SUCK!" from down the hall. :)
Reminds of a time a friend and I were playing Doom 2 via dialup.
I was loaded up with weapons, and I hid directly behind a doorway waiting for him to open it. I had him. He was dead, but didn't know it yet. I could have used the pistol or knife, but NO, I had to choose the BFG (I really wanted to blow him away).
He had no idea where I was. When he finally open the door, I laughed and fired the BFG, but before it got him, he killed me with some small weapon. Totally ticked me off! The BFG took so long to load, he had time to shoot me 3-5 times before I could get him.
I can't believe I still remember that after 8 years.
