Should I grant your wish with the catch of the vehicles only being used with escort missions? Because that seems to be the popular thing in the most recent line of posts here… ah sure I will. You can have your wish, but all the vehicles are now tied exclusively to crummy escort missions.
I wish that, in an upcoming game, you would get to fight an evil Zoni boss (maybe even as the main baddie).
Go and play some LittleBigPlanet, it's good for you!
