It's not a wargame or an RPG. It is a computer game with a fun twist. It is Not a Game, yet almost everything in it is game-related. It is more of a puzzle-style game like Myst and others before it. It is old and has been out for quite some time. But my son recently introduced me to it, and I easily lost four hours without missing a blink. It is definitely worth looking at if you like puzzles and different viewpoints.
