I had an idea for future content for the band.
--repeatable Band "gigs"--
-another method to earn money for the non-cheaters. Or a possible job if you get fired from the office.
-if the band harem is active you could have possible sex events for the band members (either together or individually) for after or during the gig. Maybe make a non-band girl a "groupie" of sorts and have her participate in the sex.
-you have to keep your practice up in order to make more money from the gigs. Similar to how the office work percentage decays but at a faster rate. Also in keep practice up in order to gain enough fame for better gigs (Fame bar?) Similar to Palla's job management; better percentage means better gigs but has similar chance of failure unless practice is kept up.
If you all like these ideas feel free to add your own thoughts and get Andreaphis to take notice.
