BLOCKY LEVELS!

In the recent interviews I always hear the word blocky levels!
For instance in the reviews of NOLF TECH DEMO I heard the that it still has blocky levels!
WILL DOOM 3 ENGINE DO ANYTHING TO ELIMINATE THIS PROBLEM?????????????????????????????????????????

Hm sorry, what does it exactly mean, blocky levels?

I think blocky level mean the old square room and not real curves in the environment. Well Doom III will use the Quake 3 engine, or a more powerful version of it, and we see that Quake III can make levels that are not like running around in boxes like Doom and Doom II. Now I am not bashing Doom at all, but with todays technology there shouldn't be any blocky levels.

So Dima hasn´t seen any Q3A map until now? Maybe the next question is "will the Doom3 engine be able to show 3dimensional enemies"... :)
