I think a lot of it has to do with how the Ouya assigns devices. Why in the world when you pair a second controller, and then cut it off, and pair another one, it makes that controller NUMBER 3, instead of filling up the second slot.... it's frustrating. I really wish they would look at trying to come up with a solution to make it a lot easier to assign controllers / devices into controllers slots, other than the method they currently have.
