I already spent 8 hours so far. three main missions completed. the game is just amazing. technologically, skyrim's new game engine is freaking awesome. I still wonder how developers could put more than 100 hours of gameplay in just 6GB. their texture compression technology is just unbelievable. ID software (Rage) should learn from Bethesda. now I realize that the size doesn't matter.
System Shock took me well over 100 hours to complete and it fit on a 640 meg CD; there was also floppy disk version that was only about 20 megs -- I can't recall how many discs were in the box.
AND, you can reuse textures OVER and OVER and OVER, which I've noticed this game does.
The VO is probably a larger part of that 6 gigs, but I don't know for sure.
Anyways, good game so far, but my usual gripe... I'm on Master mode and it's been easy. Giving my character a flame-thrower hand from the get go is an overkill IMO... I probably shouldn't use it? And when the hell did I learn how to be a black smith?
Anyways, just griping. I like this game WAY better than Dragon Age 2 and I hope the challenge picks up when I get further in.
