Quoting DarkGaldred, reply 71That's a good news, because combat in Fantasy wars was much better than in Civ 5, which is not that hard, though.
Sorry but combat is still like civ 5. Engine is not the same as combat mechanics.
But why would they drop their own combat engine to borrow the inferior civ5 mechanics? That does not make much sense
From what I recall, Fantasy wars had unit casualties replacement cost, defensive support from archers and mages to adjacent units being attacked, suppresion(ie temporary damages) , and more interesting units progression (and the unit stats were more detailled).
That may have required a bit of streamlining to adapt it to a larger map and army, but not as much as turning it into an Civ 5 clone
