Game theory is mathematics, not science. You can derive the basics of supply and demand from game theory.

Economics is a soft science. But so is history and, I'd argue, a good deal of computer science.

You can derive supply and demand from game theory once you make some assumptions about preferences, costs, rationality of players, etc., all of which are non-mathematical, mostly empirical concepts.
