Idk what the resistance to KZ is all about. At its coreit has the bones of a great IP. For whatever reason its just never lived up to expectations. Maybe its better suited to be a game like Farcry or or Crysis. Whatever the case, its an IP whose main protagonist is actually the antagonist, but its also something that an entire game could be made from the perspective of who are considered to be the bad guys and it could still sell.
Hell they could even go all Dues EX on us and it would still fit in their world.
