i only played the original doom on my boss' comp at work way back when. never played doom 2 or any quake, half-life, or anything since ive only began gaming on my pc in the last couple of years with RTCW, MOH:AA, CoD, Black and White, and Far Cry. my point here is im not jaded when it comes to fpss since ive only played a few (other than demos).
i think D3 is an awesome game. its kinda like a haunted house. you know whats coming but its fun to let go and let it scare you. turn out the lights and put some good 5.1 headphones on, and its pretty intense. i find it a great balance between "tension" fear and the "BOO" factor. kinda like a blend of resident evil and silent hill. resident evil only startled me with things jumping out at me. silent hill just creeped me out, and i was nervous the whole time (i can still feel the thud from the ps controller of the characters heart when my health was low, wandering around in the school in the pitch black, having nothing but the pipe to beat the little demon babies, shudder) . D3 puts those two experiences together with great balance, IMO.
will i be playing D3 when hl2 comes out? no, because i will have finished by then, and ive never played a game twice. no point in it to me. havent tried multi yet, so i cant comment on that. probably no tho, because i prefer the military shooters with objectives.
ive upgraded my because of D3, but not specifically for it. i want to be prepared for hl2, stalker, and the other upcoming games and subsequent mods.
