Gotta add my 2 penneth in and agree with what a lot of ppl are saying.
Doom 3 = Nice visuals. **** gameplay. How many times do you walk into an area, lights go down, torch goes on, enemy jumps out, enemy dies, lights go on....too many times that's what.
Cannot hold a candle to HL2's gameplay and storyline, and HL2 graphically is, IMO, on a par. More lush environments and EP1 goes one step over D3 with HDR lighting effects which, especially at the beginning of the game before DOG throws you accross the ravine, are awesome.
I guess each game will have its diehards, but HL2 + addons are far more entertaining and have far more life in them.
In fact I played thru Quake 4 a few weeks ago and near the end thought I'd install Doom 3 again and give it another chance as it's based on the same engine and was suitably impressed with it. Needless to say it isn't installed anymore whilst Quake 4 is still there along with HL2......
Suppose it matches the film in quality
AVP series was class, especially multiplayer games. Last man standing when you can hear the motion sensor but don't see anything till it's too late....that is a game that need to be updated, but what engine would you use? D3 or HL2? I gotta say D3's engine would suit the game more but it would have to be updated with HDR etc and they'd have a surefire winner on their hands.
