In our spreadsheet we refer to run time as the “standard” length of play, but this also usually means outside of endless or campaign modes. Usually referring to a dungeon crawl run outside of the wave context (for example how long it takes to beat a Hades session). If the game isn’t run based, what is the length of making your way through the average play experience. For example, a vertically scrolling spaceship arcade game might have a half hour play session if you manage to do a one credit clear.
