Well, most games with decent speedrunning communities end up being more intellectually stimulating if you get involved in that sort of thing. The amount of tech and number of strategies you have to learn to master the likes of Zelda Breath of the Wild at a high level is pretty impressive. Same with everything from Ocarina of Time to Super Mario Odyssey to any Metroid game to whatever else. Heck, if you want the equivalent of a phD in either Super Mario 64 or Paper Mario, then videos by pannenkoek and Stryder7x are fascinating: https://www.youtube.com/user/pannenkoek2012/videos https://www.youtube.com/user/pannenkoek2012/videos https://www.youtube.com/channel/UCYDnJiF0_RqSjkjvjRbG1tA/videos https://www.youtube.com/channel/UCYDnJiF0_RqSjkjvjRbG1tA/vid... I suspect competitive Pokemon would probably be pretty intellectually stimulating too, if at the level of Smogon or the world championships. There are a crap ton of tactics in that series, and trying to anticipate your opponent's own strategies while countering with your own requires a lot of creativity and thought.
