OK...if I understand correctly, Jazz3D was cancelled because a)CEOs(or whoever's in charge in a game company) didn't think it would be profitable and/or b)nobody was being paid a cent....
Roughly what amount of money would go into the salaries of a team developing a game like Jazz3D? This is pretty movie-ish and naive, but if we could bring Jazz3D to the attention of enough people, maybe everyone(who has money to spare, of course) can pitch in with a small amount and lots of people contributing small amounts eventually puts together a large amount...
This is just a random idea, and it surely isn't the only way to get Jazz going again...I just thought it wouldn't hurt to casually mention it(and hopefully start something of a discussion)
