My nephews are at that age too, the youngest of the two just turned twelve and already moved to the next school.
I'm not sure if he still plays with playmobil, I know his brother doesnt anymore though.
Currently I have no one in the family to give playmobil for their birthday. Well my niece is two and a half so she will get some 123 playmobil for christmas from me, but 123 isnt the same. She just does not really play yet, mostly just tossing stuff through the room.
Personly I was 15 before I truly put it all away, before then I still felt more like a child than an adult.
