Completed the main story line. Be careful at the very end I'll be giving this game another play through but this time I will use the big guns more than sniping. Also a friend has just bought the game so I'll be playing co-op which will be nice. Seems multiplayer is a joke unfortunately due to lack of dedicated server. Can't say I have felt sick from the motion blur while using any of the vehicles. I have heard of people getting affected in this way by games though. Sleeping Dogs is one example.
