I keep seeing "Doom had X so that's why it's okay to have it in Doom 3!!"
It may just be me, but that's kind of a dumb argument on two seperate levels. First of all; the original Doom series had pratically no storyline in-game.. Should they have carried that over to D3 as well? id didn't seem think so. They must have felt that having no story in a singleplayer game is a relic from a dead era of gaming and thusly adjusted to more recent standards. So why bring the rest of the stupid, trite, 1993-era gaming concepts to the new game when you've already shown your willing to cut stuff because, you know, it just doesn't work in today's game.
On the other hand; there IS something to be said for retro-gaming.. Some people think it's cool, more power to them. I could accept it if Doom 3 was just Doom with 2004 graphics.. Too bad it wasn't. The game, hell, the ENGINE was never designed to be Doom. Doom 3 is MUCH MUCH slower than the frantic monster hordes of Doom. IMO, Doom 3 failed at bringing Doom into the 21st century and it failed at being a retro-gaming experiance. It just couldn't decide what it wanted to be, which ending up hurting the overall experiance.
And that's to say nothing of the boring levels, crappy monster placement, infuriatingly lame gameplay designs like the flashlight and a horribly unsatifying resolution to the game. (Between the last boss and the ending cinimatic.. Yuck..)
That being said, the game was ultimatly good for a single run-through, if only to see what the next monster looks like. If the expansion gets favorable reviews I might check it out. Here's hoping they make something awesome.
