*Scratches head*
As far as I understand is more down to Porsche to decide who will give the license to who, I hearing a lot of this "boycott" thing about this but meh, they don't work, and this one is no exception you see:
>It requires you to stop buying the products of the company that makes the game(either EA games or Porsches(laughs)).
>It requires also an organized petition and proper media attention, which doesn't have and will not have in the upcoming months because of the recent boycotts against Origin and BF3.
>It requires a lot of people, at least +5000 to gain enough notoriety, as far as I can see they have only managed to get around 400-500 signatures, which means that it will take plenty of time and organization to gather enough people to make the boycott effective.
I seriously doubt that people will stop buying BF3 because of an unrelated boycott, the same can be said about NFS The Run, the market for that game is very different, and not being the same market makes this task even harder.
Conclusion, boycott Shift, and even so its unknown which part has more to do with this, I say Porsche but I don't known who controls these licenses and how the licensing works for these games.
