I don't think I'd trust myself to create my own virtual world. I would hire Jim Jarmusch to do it. We'd spend some time together so he could get to know me a little and then he'd come up with something. I think it would involve aspects of the movie Sin City combined with a Tropical Island made out of endless Desert Island discs. I'd be a master bartender able to concoct any drink at will and I "would play the guitar play just like a ringing a bell." Go go.
