I've become used to games like Witcher and Skyrim and Mass Effect, which go on for quite some time. My first play lasted a month, playing on and off, but the second one was only three days of playing. Great game, though. Next time I'll try a different character, more gun oriented.
Now I'm playing Riddick. Lots of good sneaking in there, too.
No fancy-pantsy Elven dagger-twirlers. Just tough guys.
