We need a new project seeing as the last one didnt turn out well.
I suggest steampunk city.
A perfect example of steampunk style is Bioshock
That might prove troublesome. Choosing a certain style rather than an overall theme makes it difficult for everyone to participate. Some people might not be able to build in that exact style, where a theme will encourage more people to join.
That being said, I love the architecture and style of the buildings in Bioshock, and I've often wanted to build something along those lines. Underwater, perhaps?
