Almost all countries have ratings based on age, even the US with its inane E,C,T,M,AO,X,EA,FOO rating system. I've never seen anyone proclaim some game is for kids based on the USK rating here, though. They'll complain about graphics or content but never about the rating the USK gave out. The only ones who even notice the FSK/USK ratings are the children prevented from buying something and the parents who don't want their children to play "evil" games.
