A 54-year old man from Michigan was arrested and charged with misdemeanor assault and battery after he hit a female friend in the head, breaking her glasses. It seems while playing a game of Monopoly, he got upset when she refused to sell Park Place and Boardwalk to him.
That seems a bit extreme to me.
Although there was this one time when I was playing the game Risk with my brothers when I invaded Irkutsk and one of them threw his red dice at me. But it never really game to blows and police didn’t need to be called.
