orcishgamer: That's a good trailer, if that isn't just polish one one section that is unlike most of the rest of the game, DE3 could shape up really well.
lowyhong: My only concern is that the map may be too small. I like how in DX there was a lot of tension because you didn't quite know what was coming; at the same time, the level designers managed to not make every empty corridor feel redundant. Everything was there for a purpose. I hope they maintain this in HR.
The small areas in IW were due to the original XBox's limitations, I think we'll be fine. From the close-ups I've seen the graphics are a bit dated. Clever level design can make even small areas look big (e.g. Silverpines in Fable 3) and through clever loading you can actually get some damned huge areas going (e.g. Mistpeak Valley in Fable 3). I would hope the PC players would get a texture pack to make it look a bit nicer, after all, there's no reason for them to suffer with 5 year old graphics.
