The Longest Journey was "designed" by Ragnar Tornquist and he has a blog where he writes about games (in general an also about his games), about movies and his current project.

You can find a lot of information about "Dreamfall: The Longest Journey" at his blog (he recently wrote 2 parts of a "post mortem" about Dreamfall and more are to come).

Loved both games, but I must warn you about Dreamfall. You can easily get attached to the characters, and when I finished it I was in a "weird state of mind" for a few day...  (not sad, well maybe a little, but there was just some kind of weird feeling and I cant describe it)
