It isn't a question of "cutting down strategic possibilities" because there is only one path to victory, namely grab every minor country you can, with no consequences. Terif invented the "Terif cookie cutter". This so wrecked SC1 that it was necessary to add MPPs to the allied majors to rebalance the game. Right now the U.S. always enters no latter than summer 1942 no matter what the Axis does, so why not grab every minor for plunder you can. And with only five chits for diplomacy each side usually tries to cancel out the other when they see a move being made to influence a country. And once the U.S. enters diplomacy is out the window, assuming there are any unconquered minors left. And when we see things like England attacking Ireland or Saudia Arabia or Germany attacking Switzerland with NO consequences it isn't a game with "strategic possibilities" it's a Harry Turtledove novel.
