I literally played through the first two missions, messed around with free exploring a little, and put it back in the envelope and sent it back. Less than 20 minutes total game time. It's that bad.
Do you like GTA? Burnout? Saint's Row? Don't get this game. It's nothing like any of them.
Do you like "Pimp My Ride"? Get this, but only if you don't like pimping your ride, just driving around in an ugly one while Vin Diesel spouts off lines that sound about as inspired as a dog coughing up it's lunch.
