A Doctor Who game

Feasible -- Though Doctor Who has the ability (well the Tardis does) to step backwards in time whereas working the OP's initial thread's ideas, I was operating more on the idea of everything moving forward i.e. time, space, evolution etc

Yeah sure, though simulating grand scale movements along with suggestion to watch civilizations rise and burn sort of brings time travelly stuff in mind. A god game would be nice but OP suggest travelling, plotting courses etc so i don't think that is what he plans to do.

Would stepping backwards in time be so hard. It is essentially same simulation in backwards. There would be some time paradoxes to tackle of course.

But i think we are both straying away from what he wants, since we are not sure what he wants to create. He mentioned crafting economy etc. Is this going to be a strategy game?
