I'm overjoyed that my lowly, Athlon 2400/FX 5700 Ultra setup is running the game with no glitches at all. Actually, I was hoping that it wouldn't be able to do so as I've been looking for an excuse to upgrade.
AvP2 meets Resident Evil is my preliminary take on the game, although I'm still trying to decide which game has frightened me the most (Avp or Doom). After all, the fright factor is the only thing that could put an FPS title above the rest. As others in this thread have mentioned, there is nothing new or revoloutionary in the game.
On another note, I love how the guys at EB ranted about how the game was sold out EVERYWHERE and that fools such as myself who neglected to pre-order were going to have to be left out. I had agreed with them until I walked into Wal-Mart and found their own DOOM3 display with about 50 copies in it....
I'm enjoying DOOM, but I still find myself reaching for Black Hawk Down in its place sometimes...
