I'm curious as to how you got 50 hours out of this game without completing it. I think I exhausted two-thirds of the content in the game, and completed the main story, in about 30 hours.
I like the game a lot. At the time I think I would have given it a 9 out of 10. Now, in hindsight, I think it's probably an eight. I'd say a very good game, that falls noticeably short of great.
