Well, I don't know what you mean by Fur Fighters being limiting, but as I haven't played the Jazz 3 demo, and as Fur Fighters is the closest game that would resemble Jazz 3 (what with cartoon animals with guns) that is why I said it should be like it. Please elaborate on how it's limiting. Certianly Jazz 3 could add more to the concept and make a better game out of it. It would be very much a 3D platformer, except Jazz would shoot the enemies (or stomp on them, or whatever like Jazz 2), and unlike Fur Fighters, the view shouldn't be limited to seeing the character's back. A full view should be allowed.

Well, whatever cause them to get annoyed and less interested we don't want to do. But what can we do then? Maybe they'll fail at their other projects, and realise Jazz is the way to go. Make a lot of money on a well-known franchise before you try something new with not enough money to risk.
