In my opinion this is the best crash / off road / racing game out there currently and I have made some sweet vehicles since owning this game. One problem with these vehicles is, there is no way to switch from Four wheel drive to two wheel drive without opening the vehicle menu and taking out the front differential. This also applies with locked and unlocked front and rear differentials. what im saying is, is that it would be freaking awesome if the Devs. implemented this design into the game in one of the future updates, so you can switch on the fly without having to stop for 30 seconds to take out a diff or switch to an open one.
