Ugh, I hate Doom 3. I didn't get too far in it, but the flashing lights with pitch black rooms that are filled with guys at every corner test on my patience for a good experience. Without a flashlight mod, I wouldn't have even got to where I was in the game.
As for Call of Duty 4, it may be short, but I loved how the ride of the singleplayer campaign felt better than most other FPS games out there. Something about how well they implement everything around you to mold this intense and exciting experience is what keeps me coming back to play levels over and over again.
Also, like Battlefiled 2, I like lots of stuff going on in multiplayer. That's why I like to play the Ground War mode when I rent it for the PS3.
