Peris, true, it's got some issues in places with really low res textures sitting next to nice high res ones but I think the overall effect they've achieved is fantastic. The lighting, pfx, sound and environment design all work together so well that when I was playing it, I was pretty much blind to the faults. It's only now that I'm playing it a second time and taking the time to look at the environment properly that I see these things 
Dux, when I get Doom 3 I'll add some screens from that too. Unless you want to take a few good ones I can use? I'll put your name there and a link to you if you do
