Well the core tenant of Bioshock is that there's an independent city who's visionary has a deluded ideology that bleeds all the way down to the populace and you're an outsider brought in to complete a task that runs against their leader.
A modern day setting but with a city that lives according to "old fashioned" ways of life could be interesting. A cult of protestants might be too similar to Infinite, though. I'm thinking something like Wicker Man or Apostle.
Or maybe a virtual utopia where people choose to live a completely separate life digitally, which could be pretty meta and provide a lot of commentary on the future of technology and virtual reality.
