...but WW2 Yugoslavia resistance game please?
So...early-mid game of faffing about through minor skirmishes and sabotage missions, followed by an endgame that's more or less an escalating set of "Run the **** away!" missions?
I mean, it sounds interesting, but you'd have to do a whole lot of work to do it justice, no? Can't really think of a game that properly rewarded you for organising a successful fighting retreat.
