Just got the game yesterday, my god it owns.
Imagine Oblivion, remove leveling up and replace the fantasy setting with a... I dunno what it is but it's so right.
First game I played in aaaaaaaages that is actually hard, you are just as strong (and in most cases weaker) than you enemies and the game can be scary as hell in some parts. F.E.A.R. scary, except less cheap and doesn't wear off.
Also you can't just leap outa bushed, rambo style, and kill everyone. I've lost 1 on 1 encounters alot.
The graphics are amazing but the mega plus is the sound, you can hear the faint sound of howling in the distance while standind at a camp fire which has fellow scavengers playing guitars, brilliant :'(
Screenshot to really sum it all up:
The sky is dynamic btw ;)
