"Mature" alternative to GTA :-)

We have long been looking for an alternative to GTA ...... because the junior is just too young. In forums was referenced as the only possible alternative to this game again and again. Otherwise is apparently really nothing (that is family safe) in question. Although was skeptical, but the junior is now happy and has fun with it. It's really very similar in many areas.
USK 6 I find not quite fit, but the next is yes then unfortunately only USK 12th
But not suited my opinion, for a 6-year-olds, which is for me the series but not .....
From us but good and therefore 5 stars because it is the perfect (and, moreover, Funny) GTA alternative is for a 10-year-olds!
