Realtime Worlds just released APB, but it's already hard at work on its next huge project, which appears to be a ... real-time world. "Project: MyWorld," which RTW expects to release "early next year," is a social platform based on a detailed model of the Earth. Players can build structures in a virtual version of real space, and open those spaces up to interaction with friends. The teaser trailer (after the break) shows one user commenting about a "fishing game" in a structure, for example.

The trailer also suggests a number of ways to interact with the real world from within MyWorld, with Twitter, Facebook, Flickr, Google, and Loopt integration shown. "What would it look like if Nintendo built Google Earth?" the website asks. It wouldn't have this much online functionality, that's for sure.

Update: Realtime Worlds clarified to us that MyWorld isn't in itself a game, but is instead a platform for game developers to create new social games. It's not a consumer-level product.
