Steam is killing me this weekend. First they have every X-COM game
for $13.49. I only ever played the demo when it was out, and a lot of people have this on their "best ever" list, so it's about time I got to play these.
Then there's 50% off the id super pack
which is nearly every id game and map pack for $35. I'm still considering this one. It's a phenomenal deal, but I already own all these games except for the Heretic/Hexen series. Aside from Spear of Destiny, I never played any of the DOOM or Quake map packs however. It's this weekend only, so if there are gaps in your id history this looks like the best way to fill them.
(When is LucasArts going to get its act together and put ScummVM versions of its classic adventure games on Steam? Lots of money for very little work!)Update 5:56p:
Bought it. WORTH IT. I downloaded the latest version of zDoom and it detected everything automatically. Works like a charm, and runs a bit better than DOSBOX :)
