(At least at first.) i wouldn't consider anything a true RTS unless it has some type of resource gathering and tech/unit building element to it It would have that, but in the form of unit recruitment or negotiating with and giving advice to nearby lords. (Perhaps local lords could grant you use of their smithies, craftspeople, and peasants for support/logistical tasks.)
