Wargamer → It is formed from "war" (from Old English *werre*, meaning conflict or battle) and "gamer" (from Old English *gamen*, meaning play or game). The word "wargamer" refers to someone who plays games that simulate warfare or military strategy.
Think of someone who engages in 'conflict' ('war') through 'play' ('gamer') — that's what a wargamer does.
