Also "default" is another good term with special significance gaming. Default settings, such as the control scheme, the difficulty, the other parameters of play.
And difficulty is interesting in its own right. I just recently played some more of Death Stranding, which I was playing on hard without serious difficulty, until I got to a certain part of the game that I was unable to finesse on that difficulty, and thus had to stoop down to normal to get through it.
I find interesting this notion that there are parallel versions of the universe of the game that have slightly tweaked parameters, or have even introduced new ones: the enemy behavior is less tactful, their weapons less accurate, the regeneration rate of the player's health is slower, etc.
But what I really find interesting is the psychological impact of these games, how they may impart a certain logic to the maturing minds that engage in them.
