wasnt going to buy it as i was waiting for battlefield 4 in november. ended up picking up a laser burned copy for €20, gave it the toothpaste treatment, ripped it to the HDD and no issues thus far.
as for the game though, i have only few hours up on it and a few missions but so far its entertaining enough in a gta way. large map and you can alternate between character's for different missions. each character has its own special ability you can activate at certain times.
the cars are pretty fast also and the road network through the city takes some negotiating at peak traffic times

.
ive barely scratched it but so far its looking decent.
