Do you think it holds up, I for one still jump at the game but the save system with its odd auto save thing just ruins it now adays for me. any one else think the same?

A lot of people here hated it. I didn't find it bad, but it wasn't good either (Xbox version. I can't run it on here.). I did enjoy Hell though. =)

It was better once you got the duct tape mod. It's an ok game, good tech demo, but it won't stand up to the test of time... in fact I'd say it's already failed that test.

Well, I like it, and it still looks pretty great.

It looks great (still), and it is beautifully optimized and runs on pretty low-end hardware.
Despite this, Doom 3 felt a bit more like a tech demo for ID's newest engine than an AAA game.

Can't see your problem with the autosave system, when there's a manual same system as well.
But anyways, I enjoyed it. The game itself was fun enough, but there are also a lot of cool mods for it.

It was fun but it just didn't hold up to my exepectations after ID's other Successes. Hopefully Rage will be their coming back title and so far it seems to be shaping up to be so. I'm getting excited like I was for Doom3 though so I'm gonna scale it back just in case it's another disappointment.

Can't say it's better than the previous Dooms in gameplay, but I had more fun with it than most other FPSes that year. Especially Half-Life 2. The only game I enjoyed more than Doom 3 was Chronicles of Riddick.
So you can say Doom 3 was the 2nd best FPS I bought that year. Playing it with headphones at night was awesome.

I thought Far Cry was pretty good that year.

i fully enjoyed Doom 3 and the expansion

I actually enjoyed Doom 3 more than HL2. I own both, but have replayed Doom 3 more times and more often.
I like the classic feel of the gameplay, even though it's slower and full of excessive darkness if compared to the original Doom.

My opinions are like my preferences for beef. Medium rare.

The expansion was great, wasn't it? I didn't like it at first - thought it was more of the same. However, once I got the artifact, I had a blast. It was just amazingly fun pumping bullet after bullet into enemies and watching them die, all the while still with the possibility of yourself dying.

I absolutely loved it. Great horror game. Reminded me of System Shock 2 more than any other FPS to that point.
Less FPS-ery than the other games though.
I also thought it was significantly better than HL2, which I think is good, but massively overrated, even if IMO it has the better engine.

I thought it was okay. I never finished it; I got to hell (or some hell-looking place) and had gotten tired of it by that point.
I think what really got to me were the spring-loaded monsters. Any time you saw a box of ammo or a medkit in a closet or a dark corner, it was a safe bet that touching it would spawn something behind you. It was very predictable, and it got real old. It got to the point where I would spot a pickup and think to myself "Hmm, how badly do I need those 10 shotgun shells? Last time I picked up one of those, I used 20 machine gun rounds to kill the imps that spawned. Is that a fair trade? Nah, my shells are almost full, it's not worth it."
That was okay in Doom 1 because it was just a run-and-gun shooter; as long as there were monsters to shoot, it didn't really matter where they came from or why - but Doom 3 was trying to be more sophisticated than that.
