Rather, I think it’s borne of necessity to onboard you to the game mechanics. We certainly have a bird brained instinct to catch the worm / win a round, so a good game design cuts you some slack to begin with, so you can have a little dopamine as a treat
From there, difficulty should scale up so you don’t always win, giving you that “intermittent reinforcement“ that makes games addictive
One of the reasons. I'd wager this is what appeals to people not merely playing but mastering a particular game - playing higher difficulties, 100% completion, and so on.
The other reasons would be overcoming other humans (esports/pvp multiplayer), discovery (story driven and exploratory games), and just passing the time (casual games).
