One thing I see these days in games is that developers say that their game is going to require/need/revolve around co-op/stealth/strategy but they never actually integrate what they want into the game.
Usually it isn’t even part of the game like H3:ODST was supposed to be more stealth based and it completely failed to be a stealth shooter it wanted to be. Occasionally you will see a game that does what they want perfectly, a good example of this is L4D it’s called a co-op game for a reason, it’s not just your buddy tagging along with you, you actually need to co-ordinate with your group and work together.
The mere fact that some games don’t manage to do what they want correctly makes me be skeptical whether SP:C will actually involve stealth as much.
