He who said JJ3 wasn't all that anyway - you mean the illegal demo? By today's standards the game has too few polygons anyway. If they decide to make JJ3 it won't neccessarily be just like the demo, though what I say about the demo is limited since I've never played it. They will likely start from scratch with the game, or improve on it so much that it hardly resembles that early demo. So don't just look at that demo and determine whether this franchise has a future or not.

And, you could also tell people you know who don't have JJ2 to by it. You would have to help them get a copy, and I don't mean by burning a copy for them. There's always room for more fans and more people who want the series to continue would be a good thing. You'd be surprised how long in a game's existance you'd see newbies online. But I guess I don't have proof of that myself, other than just getting into Jazz 2 online play recently myself.
