I got it for $1 and I -still- felt ripped off.
AND I ONLY PLAYED THE INTRO. :(
I got no problem with DNF, I like it. It's an old school shooter, nothing more.
Here also, I really enjoy it AND I bought the Dr. how cloned me DLC. To me it´s much more fun than a lot of other shooters, like Doom3, Vivisector, etc. It´s just the linearity that bogs me but well...
