And I have to say (for what it's worth, and please don't see this as condescension), good work! Even considering the fact that quite a bit of the visuals (denizens, building interiors, etc) were taken from previous MM games, your efforts show that where there's a will, there's a way.
I personally think MM9 would have been much nicer (visually, at least) if it had a game engine like what the demo used. Of course, I have read that the Lithtech engine is capable of far more than what can be seen in MM9.
Anyway, kudos to you. Wish I had your skills/aptitude for programming and stuff.
