You play it casually just like you read a fiction paperback casually.

In the annual interactive fiction contest, the judges get 2 hours to evaluate ba game. So many new games aim for that to be the playing time.

From what I remember some old Infocom games like Enchanter (which takes place in the Zork universe) don't take very long to finish (definitely less than a standard $60 video game console video game).
