wow, I'm gone for a few weeks for some exams and miss this whole event. My thoughts have already been posted by most people here, but there is one aspect of this that seems just a bit fishy. Why exactly is he posting these things on internet forums before working out the details with Interplay and getting a publisher for his game? Aren't these business deals generally done secretly and publicized only after they have been carried through?
Anyway, I honestly don't care much what happens with this. If he manages to make this good, we get what we have dreamed of for years, and if it sucks (from the reviews I've seen for his previous games and his ideas for this, this looks very likely), we ignore its existence for our purposes. It's not exactly going to be a commercial hit either way given the relative unpopularity of space sims.
