I guess they were inspired by a very similar law in Greece from 2002[0] where in an attempt to outlaw illegal gambling done in arcades a poorly written law outlawed all games (the article mentions it was in was in public places but IIRC the law was for both public and private and the government pinky promised that they'll only act on public places). I remember reading that some internet cafes were raided by the police too :-P.
