A common term in board games (and at least roguelike games) is “coffee break” games, which usually take ~5-15 minutes. I remember going back as far as the 00s, RPG games that didn’t have at least 40 hours of gameplay were criticized as being too short. Is there enough room between Flappy Bird, “coffee break” games, and epic (J)RPGs for a lot of terms about how long a game takes? And what do you mean, like a session? A run-through? There are games where you don’t have access to a save point all the time, and others where you can just turn it off and walk away and later it’s exactly as you left it. There’s that game Desert Bus that takes ~8h but you can’t even really stop to use the bathroom. There’s games that have more or less replayability, or dozens of hours of depth that you can explore but only if you like. There’s so much more to the medium than there is to books. I don’t see how it’s necessary or useful to use a length metric to describe games. It feels like asking “how many pages long is this game?”.
