Completely independent day and night cycles, orbiting entities, COMPLETELY dynamic lighting, not to mention the attention to detail in that map is just extremely good. The only thing that'd make it look better is soft shadows...but that'd put the framerate somewhere in the negatives.
Personally I liked Doom 3 better than HL2, because HL2 was just too boring...god that stupid buggy part was so lame. But I'm not going to berate anyone for not liking it. I'm just going to say this--at least Doom 3 will live on. I'm gonna tell you right now, though HL2 brings in revolutionary facial positioning technology...wait, that's ALL it brings that's revolutionary. The physics engine is outsourced (no pun intended), the lighting is just as good as FarCry's, not to mention its lighting's fairly static. Doom 3's inhoused technology is going to be a lot easier to develop for, and hopefully end up with better games which use the features to a fuller extent. For example, if I'm not mistaken, on that video they take advantage somewhat of penumbra lighting, etc.
I just can't wait to see Quake 4, RtcW 2, and id's next venture.
