allright, I addmit it- I'm an ignorant fool! I have comletely no Idea what a combat sim is.
if you mean a solider simulator (like flashpoint): I think it should be called FPS.
if you mean a level based simulation, focusing on indivual soilder skills and morale (sudden strike, Squad leader): that's tactics
if you meen large scale war simultaion, focusing on lagre formations and suply routes (panzer general, red lightning, operation europe): that's a wargame.
finaly if you're driving around in a tank: that's a tank sim.
... and then there's 'Harts of Iron' and the likes, my best guess would be strategy, but if you called it a sim, I'd know why.
I hope this will help you answer my question. TUiA, a1s.
