I would love for PES to have contracts with every brand whose kit design is currently used by one of the teams in the game. That way, you could say you have 30 Adidas templates to choose from when you create a team, so all you have to do is change the colors to match those of the real team.
But that's too far fetched, and the PC-like editor is a much better idea (which I still don't know why it hasn't been implemented on PS3 and Xbox). Regardless, I signed the petition, as I truly believe that a game which has every possible license won't work as hard making a decent football game, as one that doesn't have any license, since it will probably be the one bought by customers.
