Your computer takes a 5-minute nap and then wakes up screaming. It either finishes everything in a flash or just gives up and crashes.

I was fighting a goblin and it took 5 minutes for the goblin to show up.

I tried to open my inventory and it took longer than my lunch break.

I was trying to log out and my character got stuck in the middle of the forest.
