I wasn't saying the Russian one would be underground, I was saying it would be a moonbase. The lighthouse could be a rocket (possibly called the Mayak), and the Plasmid-equivalent could be inspired by the whole "scienced-up supersoldier" idea of that age.

Now, for the underground one, I'm thinking of a setting waaay back--maybe Roman or Greek. The lighthouse would be something like the Lighthouse of Alexandria (except in the middle of the ocean, of course), and the Plasmids could be mythology-based (maybe not a substance like the other games). The political stuff could, I imagine, center around the philosophy of the day--or it may even involve persecution of Christians by the pagan government!

You're right about the music, though. I'd be bereft if I bought a Bioshock game without cool music. Maybe there's some way around that, like with the Tears in Columbia.
