Yeah, I thought Dragon Age was more inspired by George R.R. Martin's "A Game of Thrones" and that ilk. I kept thinking the Grey Wardens were similar to the Night's Watch, and the darkspawn were like the 'Others' of legend.
The idea of a noble betraying other nobles to cement power also has strong parallels to the Song of Ice and Fire series. But, despite the parallels, the story is pretty engrossing.
But, back to Div2, I like it. The idea that the bad guy shows up, laughs at you, and then you have to fight to survive his minions is interesting. It's really hard in places (like the first time you become a dragon -- I'm not sure I can get past that point), but it's fun.
