Hello, I looked back some pages and did not see there being a subform for this game. Madden mobile I think would be great for a subform because you could find and join a league with jsp community members. Along with this, it is a growing game and many people most likely have it. It would help to be able to post trades for people that you need and build up your team so you can destroy the competition.
If you don't know the game, you should try it out for yourself. (Is a football game) (and is fun)
