This looks like a pretty cool concept, if it weren't for the forced and awkward bioshock continuation.. Floating steampunk city? Hell yeah! Bioshock on lifesupport? Nay..
So...it's Bioshock in the sky rather than in the sea? And it's steampunk? Wow this feels so NEW. Here's an idea, put it in space, make it sci fi horror, and calling it motherfucking System Shock 3, with Shodan. Do it and do it right! :D
