Ok, I just finished Dreamfall.
The ending, if you can even call it such, is about as satisfying as the ending of... say... Soul Reaver: The Legacy of Kain (the first game)... or Shenmue (both 1 and 2)... or, hell, frickin' Star Wars: The Empire Strikes Back.
Let's just say that it's safe to assume that
when they make a sequel to
this game (and, based on the above, I'm totally certain that it's already in the works), I will be on that like white on rice when it is released. It had just better not take them another seven or so years to make it is all. (EDIT 2) It actually took them 8 to 10 years to make the sequel. (/EDIT 2)
(EDIT)
Hmm... Yeah, well, he doesn't have to convince me to play the game again. As with The Longest Journey, I'll probably be playing this one through several more times. Not right now, mind you. I think I'll be starting Kingdom Hearts in a few minutes. But I'll definitely be coming back to Dreamfall again later at some point, of course.
