AW2 - I gave up after 2/3 of the game

I got about 70% of the way through the story and then gave up. The woman was a lot of fun to play, but Alan's storylines started to tire me out, and I gave up. And I don't think I'll ever return. But overall, it's definitely a good game. I also had the problem in the first game that after a while, the night stages became tiring and boring, but the daytime stages were fun. Apparently, I'm not a science fiction fan. The more "normal" stages in AW, the better for me.
