Dear Assassin,
It has come to my attention that you want to know my opinion of Doom 3. Well, I can honestly say this.
If you sir are/were a fan of the original games, you will NOT like Doom 3. Doom 3 is a terrible letdown in comparison.
The original Doom\'s fear came from multiple monsters in small corridors, occassional dark spaces, lack of ammo, etc. Doom 3 is terribly EASY. You never will run out of ammo unless you have awful aim. Doom3 is ALWAYS dark, so therefore the dark stops scaring you after a while. Doom3 doesn\'t have the neat surroundings as the originals did..everything is metal, and gray. There is no music in Doom3. You cannot have more than 6 monsters on screen at a time in Doom3, making the battles much less intense. Monsters are less varied in Doom3..all you really see are Imps all the time. And when you get something cool like Knights after you, there\'s only one or two and they die quickly. The original Doom also had some better monster designs..the added Trites, Maggots, Wraiths, and dumb little babies with wings don\'t add much to the game. The monster attacks in general are poor and don\'t take much health away.
Please note though, I don\'t play Doom3, I just watch my brother play it. I have played the old Doom games though and prefer them very much over anything Doom3 has.
