This is based on the talking about art selling on the first page and OFB discussion on the second.
What if we made a whole market system? Yes, have essentially OFB (which would be FANTASTIC now that it's a seamless world), but also have a mall or something where you can set up a kiosk and sell art! And there would be crafts and stuff that you could do and even publish a catalog or something so that you could just mail the crafts off, but maybe you could somehow make more on the street or something (or people would pay as much attention to the catalog, so there wouldn't be as many customers)
And then, for the band stuff that we were just talking about, I was actually thinking about that last night with the music career. There could be different, though equal paths. Or maybe even just eliminating the music career completely and revamping the system. Instead of going to the theater and getting a job there, you could go up there and sign up for a list of people looking for bands. Then, you'd have to do all of the micromanaging. Maybe a band member would call you telling you they hooked up a gig at a certain venue. Or maybe you have to go to the owner and use your charisma skill to convince them to let your band play. In addition, they could play around with the favorite music feature- if someone's favorite music is jazz, they sure aren't gonna want to listen to french music! You could make bands and solo careers, although I think it could get pretty complicated, so they'd have to limit the scope and expand on it in other expansion packs. (or use my idea of mini-expansions in the installer)
I feel super creative today and I love it.
