Why not? It didn`t stop great U.S.A Directors from making awesome Nam movies did it??? Platoon ring any bells?? Apocolypse Now???? Full Metal Jacket?????? These movies made alot of money. Great U.S. actors supported by huge num,bers of U.S. movie goers at the Box Office. ;p
A cool game dev team would do it. And it would sell. And be fun as hell.
