Yeah the atmosphere is what got me hooked in the first place. I will admit they overdo it a little bit with the jump scares, but I think it does a decent job adding to the feeling of unease. The first couple times I played it I remember being VERY nervous about progressing to new areas. The flashlight shenanigans in the original version didn't help either. There's a VR version that I really wanna try, seems like it'd be a good game for it. Now that you mention it, I've definitely heard people say that about 64 being the "real" Doom 3. Kinda reminds me of the Code Veronica/RE3 thing. I'd like to play it on my N64 because original hardware etc, but I'm guessing the recent re-release is probably superior in every way.Doom 3 is certainly an interesting game. Not quite like the other Doom games but that's fine. I actually started it last week, the atmosphere is what really gets me. It scared the shit out of me. I've enjoyed what I've played so far. Doom 64 is also unlike the other doom games, it's very puzzle based, lots of action and murder still, just a lot more thought put into level design, I think. Some people consider it to be the "true doom 3", and I can see where they are coming from, but ultimately doom 3 is doom 3, lol.
