So let's say...

That a person or persons were interested in creating a journal for a role-playing game.

Say these people or people wanted the "good" band (your Barbie and the Rockers, your Jem and the Holograms, your Gomez, if you will) to be comprised of two vanity-band leads, a breakdancing wonk-sexy tough guy, and a hi-LARIOUS comedian on drums (like Ringo...only funny! JK, Ringo, you can take me to Shining Time Station anytime). And you wanted this boy band to face off against other awkward vanity bands and/or an old-tymey villain named Pants Clutchstein (Mandy Patinkin's evil alter ego).

How would one set up such a game? Would there be a vanity band or embarrassing yet secretly delightful celebrity you'd like to see guest star?

Just hypothetically.
