Videogames are full of loops. Often, the loop isn't just a loop in space but a loop of labour, a loop in time. It's a repeated task with a touch of variation from cycle to cycle, typically associated with a character progression system of some kind. The classic one is the town-dungeon loop in an action-RPG such as Diablo 4. You sally forth into the depths with sword and shield, slaughter a bunch of blameless goblins, then orbit triumphantly back to the village square with its 24/7 forge and bustling adventurer's guild. Then off you go, once again, with a Sword +1 and a shield now bearing a Goblin Magnet. There are straightforward equivalents in multiplayer, especially in the wake of Call Of Duty 4: Modern Warfare - sign in, play a few matches, harvest some XP, unlock a new laser sight, equip it, play a few more matches with +5% to your aim.
