Well, until yesterday I was running a PoS that my folks bought back in 2001, so I was kind of forced to. Right now, I am currently in the midst of playing (at the same time; this is just the "old" games. I define old as released 1980 - 2000)
The Elder Scrolls: Daggerfall
System Shock 2 (for the umpteen millionth time)
Betrayal At Krondor
Gabriel Knight: Sins of the Fathers
Baldur's Gate Trilogy (A mod that make it possible to start Baldur's Gate and play clear through to the end of BGII: ToB. This will take a while.)
Ultima IX (This game is crap, take it from me. I'm only bothering so's I can say I've beaten every Ultima game)
The Longest Journey
I actually prefer the games that came out from about 1988-1999 over modern games. I think we have too much of a focus on whizz-bang pretty graphics. With the exception of a rare few games (Portal), there's hardly anything unique or interesting on the market. Most of the ones that are interesting (Spore, Force Unleashed) are massive letdowns. So I do play old games, but not because I'm broke. Alright, yes, I'm broke and I can't afford new games. But I do play because I genuinely enjoy old games.
And yes, I believe there still is an online Doom community.
Elvalia, I have the Ultima Collection. One of the best buys I ever made. I will say, I actually prefer the first one and VI to IV.
I would say the game that sparked my love of games would be Castle Wolfenstein, on my Dad's C64. I still love that game to this day, and defend it against the morons who think that Wolfenstein 3D was the first in the series.
Vote Pieces for Pope! She didn't buy me off with the funny hat, I swear!... She made me a cardinal.
