The game brings a lot of fun, at least in single player. The world is huge. Although nothing like the San Andreas world, but it takes forever to explore it entirely on land. The missions are quite varied, the three fundamentally different characters so that you can have fun while listening to the mono or dialogs (if you still can concentrate on more than playing).
In the tuning workshops only thing missing is the speed tuning. The sense behind the way to improve the acceleration by more PS not to affect the speed, I remain hidden.
That's all there really is not to say. Except maybe even a word for graphics: superbe!
The only drawback: The Multilplayer
Here's some completely bugged and partly almost unplayable. Added to the Rockstar comes here as a sort of pay to win system builds. The money you can even earn quite normal but lasts much longer and is annoying due to the somewhat monotonous missions in Multilplayer.
All in all, it is worth the money, as the single-player save a lot!
