I prefer to play both of those games over rotation, but if you want to bring money to the players though spectators, those are currently the wrong games.
It would take a long time to educate a large enough audience to make them commercially successful. However we have the example of snooker, where there is the occasional safety battle that goes for 20 minutes with no score, except maybe points for fouls. The fans are smart enough to follow along with the problems and tactics and admire the skill needed.
I dont think the hurdle is as high as you do.
Let's list some of the things that were simplified for the masses in the early 80s
Television shows went from threes company to Game of Thrones adding nuanced complexity..
3 minute interviews became 3 hour podcasts adding nuanced complexity.
Beer went from Budweiser and Miller Lite to hand crafted microbrews adding nuanced complexity..
Bourbon went fron Jim Beam to Pappy Van Winkle adding nuanced complexity
TV dinners became hello fresh again adding nuanced complexity.
Tastes have changed across a wide variety of topics and all trend towards nuanced complexity..
The 9-ball experiment aka treat it like boxing and pro wrestling with silly nicknames and 11 round bouts with a knockout punch(9 on the break)
It failed to break big, the game was broken 25 years ago,
To think that can be overcome with small tweaks is lunacy.
Let's join the worldwide trend towards nuanced complexity..
