This is a good thread. I see the problems that your having and I would just be aware that because it hasn't been out for long people haven't yet ventured into the online aspects of the game. It hasn't even had a christmas release and this time of year isn't traditionally fashionable for purchasing games. (MGS4 being an exception)
I wouldn't be surprised if it's a slow burner for people. After many complete the Single Player mode then they will attempt the online. And (as you stated) the younger crowd may be intent on completing the Single Player in it's full aspect prior to even looking into the online.
I will add you as a friend, therefore I can play and try out your level when I get my copy of the game.
