Hmm, I think I'd be most invested in 2, 3 or 4, but 1 is also up there. Honestly, I'm not actually sure what order of priority I'd give those four. It would probably depend on the character I might come up with and the interaction potential... Not sure I've got the energy for big and sweeping, which 3 and 4 seem more likely to turn into, but damn if I don't like the details there. And the possibilities of between-city strangeness. Hoo boy, they all sound fun. 

I like Zelda games, but they're not exactly my cup of tea for writing in. And 6 sounds awesome but boggled my poor brain.
