I object for reasons other than you might think. How do they get the word about a 7 on 7 mode out there? They have to specifically advertise to American audiences. Not only is this taking away from marketing budget that could be used for features that appeal to much of their user base, but also consider the man hours put in to making this mode work. Contrast that with the amount of new players it brings to the game, and I believe you would find it an unfavorable business decision.
The same thing goes for marketing their explanation of the transfer system (this could be spread by word of mouth, it probably would take more time to write the text than it would to actually build the menu into the game.
What can they do for rivalry games? Bump up the sound and add a commentary line?
These features don't seem to me as feasible marketing options, which is why I object. Well, in addition to the fact that a 7 on 7 mode just sounds un fun to play.
