Here in the states I don’t think we have Warhammer ?
You do, but Warhammer and 40K are table top wargames with model soldiers and vehicles. Unless you go to hobby shops or the 150+ Games Workshop stores in the USA you're not likely to have come across them though toy stores used to sell their stuff but if you weren't into the hobby then you likely walked past them without noticing.
Actually Games Workshop and Geobra had a similar contempt for adult fans but I think GW has moved on and realised that the growed-ups have more money to spend and so rejigged their entire core range forcing the fans to essentially replace all their models to play the new versions of the game. At least playmobil is still the same size as it was in 1974.
