Well, the only way I can think of is somebody using the current scripting capabilities and starting building an entire game mode. A lot of things can be done already with building blocks such as

and the scripting features get extended while I develop (last additions: idle animations, syncing of time, weather, age, race and sex with corresponding scripting functions). Just needs somebody who is interested in doing something like that, I don't have the time for it.
