Ahhh this sucks. I probably wouldn't buy the DLC planes right away, but it would be frustrating to be unable to play with people just because they DL'd a couple of planes.
I know in some games like Burnout Paradise and Midnight Club there are cars available to download, but having those cars doesn't mean you can't play with others who don't have the cars.
I don't see why this game can't just set it up that way.
