I haven't ever had the chance of playing JJ1 (I can't find it for sale anywhere ). Just what kind of enemies were in it?

I also think that JJ2's enemies (but I only think so because I've never played JJ1) were quite original and ground-breaking and the only reason they got boring is because the game has been played for 6 years now. If those non-turtle lizards is going to be kept in JazzA 2, then there should be a link between them and the turtles, or we'll find ourselves fighting completely new enemies without a clue to what actually happened with the turtles (we only saw the defeat of Devan, NOT the turtle race in JJ2).

Also, maybe, just maybe, they could give Spaz or Lori their own personal adventure without any green hared intervention? Place the setting before JJ1 and let us see how Spaz and Lori got their skills/personalities/backgrounds, etc from.
