Once you know where everything is in EA, you can blast through it in about 2/3 hours getting 100% of the content you can access.
My most recent play through was 2 hours, with combat taking up 90% of that.

I really wished I had waited 6 months before buying the game, there is just so little in it. While I enjoy helping bug test the game via EA, this is the first EA I've gone through with so little content.
