Make a "career mode" that, at the first stages of the programming.. would do a character select, and a guitar select.. and the quick play.. just like the "new game" by now.. would select randomly a character and a guitar..
AND I´m not saying to do a 3d character with all the dificulty of programming and stuff..
I´m saying that.. if you note.. the light bright more as you play a note... so..
If the programmers make some unique style of character.. in 2d.. but just like a doll...
Well.. try to remeber Parrapa the rapper... now.. Separate the body with the arms.. with the head and with the legs..
Don´t need to make animations with it.. let it animate by the junctions of the body... when you play a fret... make the lower arm have a bounce on the string.. just like when you play a fret on the keyboard...
With the body.. legs.. you make something in sync with the drum.. just like in the velocity of the music.. giving it a animation
With this... you can make animations.. only with programming... using only static images.. can you imaginate that?
Make a static image of the face.. arms.. legs.. body.. remembering that type of a paper doll..
The player can make the choice of each part.. and choose a guitar...
In that way.. don´t need to be a full 3d game with complicated programing or realistic animation.. just a fun type of a game.. or making something that looks like the guitar hero for cellphones..
In that way... you can make some legendary guitarrists.. or something that remember.... for pre-made characters.. Jimmy Hendrix.. Stevie Ray Vaughan.. Edie Van Hallen.. Kirk Hammit.. and goes on...
Maybe in the future.. pick a music from them and make a boss battle

What about it? An image of all parts of the body bouncing with sync of the music and the arms bouncing when you press the buttons...
I think that´s the easiest way.. funniest.. and the python can make this..
Maybe in the future put a bass and a drummer... maybe you choose them all and name a band... and it appears in the world chart.. maybe with a pic of the band
What about it? Who´s with me?
Maybe for the drumm would put it in sync with only the low frequency of the music and the hi-hats only of the high frequency... if python accept that...
maybe.. if it works.. with characters and stuff.. put a replay mode with you seeing your band
