you want to tell me people spend a lot of time on their own playing Chess against themselves
The most competitive players do that all the time for hours per day, or those learning the game, or those who just love it—or those a week before the annual company chess competition starts
The nature of chess lends itself to solo play. It doesn't need a story or new ideas to mask its deficiencies, it is pure perfect gameplay. There are even no twists or secrets, each player has 100% information all the time. So playing against yourself is no different from playing against another human or computer—apart from you're guaranteed that your opponent is exactly the same level as you, and there's no waiting in the lobby
Of course, if you must have a story, there's the excellent The Queen's Gambit
—but be warned, there aren't any new ideas in that
But that's the beauty of gaming, there are plenty of offerings for all kinds of different tastes. Those who need constant change are likely to be less served tho, given the risks involved in developing and publishing for that taste.
There is however no need for those with one taste to disparage the offerings for those with other tastes.
