Same rule applies to video games, especially third person, 3D, single player games.

So, so many power fantasy games have enemies literally cue EDIT: queue up to fight you one at a time, only occasionally attacking you when you’re in the middle of taking on one particular person.

Less forgiving games don’t do this, or at least do this faaar less, and are thus usually much more difficult and require either stat grinding or finding a more effective strategy.
