The Sim games, Sim City etc... were always called strategy games in places where I went. Flight games, sports games, and some first person shooters are called simulators, and this has nothing to do with whether they're about shooting or not. This is also true of strategy games, Sim City and Total War games are called simulators, and others are not. It is not about the gameplay, it's about what the game is trying to simulate.
