Few days? You playing 24/7 with no sleep or something? >.>

It took me like 50-60 hours my first time to beat it, with minimal side quests. Then again I didn't use a strategy guide, so I had a bit of fun exploring everything.

But I would rate it a 9. While very good in many aspects, and I loved how it had so many of the classic elements and references from older games. I have very few gripes with the game, but at the moment I can't recall them (I'm sort of half asleep at the moment.) But I'm also a strict person when it comes to rating games. I don't think I've ever had or will rate a game a perfect 10. >.>
