My other half is addicted to it. Says it's a good step up from previous versions. The online multiplayer cops and robber game is great fun. Only played it for a while but it has a good few new features that are an improvment; a taxi service that delivers you exactly where you want to go so you don't have to drive for hours: a mobile so you get missions much easier; it's no longer necessary to have to eat constantly just to keep going. Also you are given the option to redo failed missions immediately.
One other feature I liked is that you can make moral decisions throughout the game. you can choose whether or not to kill someone, and your choice alters the game. The graphic are also great, especially the water.
