... is it even remotely possible to beat sarge on mightmare node??
Did you use the Soul Cube on him? That takes a good bit of his health away right off. Although, I havn't tried it in nightmare mode yet.
Carmack is still the best at producing game engines.
I don't know.. the Unreal people have done some good stuff as well. Their UnrealEngine3 is looking very good so far.
No the soulcube wasn't 'changed' unfornately - my bad.
Unreal3 looks very good but until we actually see it in a released game it doesn't count.
Just remember Doom3 engine doesn't limit the number of ployies, it handle very large texture sizes, self shadowing can be turned on and you can create and add any shaders you like as new matrials so realistic water and coloured lightrays should all be possible with the current Doom3 engine. It's just a question of which gfx cards can keep the frame rate high enough to be playable.
