game novella
noun phrase
A videogame with a play time between one and four hours, intended to be experienced in a single sitting. This is in contrast with a game poem (fifteen minutes or less), a game novel (ten to thirty hours), and a game epic (eighty hours or more).
As a busy adult, I’ve been really into game novellas recently. They tend to be very focused and cohesive, and are a great way to spend a relaxed evening.
