It is also a lot harder to model these sorts of dynamics and make for a compelling game, IMO. An interesting idea of an &quot;economic rts&quot; type game is Offworld Trading Company(incidentally the brainchild of the Civ4 creator). I think they strike the right balance for their type of game, but I&#x27;m not sure it could be done for a more deliberate, Paradox-style strategy game.
