I finished a few days after I got it, but I only played it in short bursts that first time. I don't mind Jazz's new clothing since I belive JJA is an alternate universe accidently created while Jazz and Spaz were chasing Devan through time in JJ2. After our heroes stopped Devan, the alternate universe of JJA split apart from the normal universe and became independant. The alternate universe was created to fill in the fact that Jazz,Spaz, and Devan were missing in the normal time stream.

And that ends my crackpot theory.
