Free Jazz Hero?
A cool feature of Rock Band that is missing from Guitar Hero 3 is the ability to do some limited amount of improv. Well, very limited.
How cool would it be to have games like these support a greater degree of improvisation? Maybe the game would rate your improv and grant points based on staying in key and your playing off of what your bandmates are doing. Imagine the replayability - each time you play a song it’s different.
Guitar Hero 4 is promising to allow gamers to compose and share their own music. Hopefully true improv is coming soon as well.
