There are tons of games that don't require that sort of knowledge base or study investment. It's a minority that do. But you're on Lemmy. This is a self selected community of extra thoughtful nerds. This community is more likely to be excited about games with homework than your average gaming community. I do genuinely love the research part of complex games. I like crafting builds and planning battles. I loved both Divinity Original Sin games and will love BG3 when I get there.
But sometimes I do just want a game for my hands to play while by brain takes a break. That's why I spent most of the summer with Earth Defense Force 5, a 9/10 space insect exploding experience. Highly recommend it if you don't want to fuck with the details.
I honestly think that's just your circle. That does not describe the majority of the gamers I know or have known. I have always been in a minority for wanting to do math in my free time and have to find places online to discuss these games because usually nobody else in my life is playing them. Most of the people I know who played BG3 did so because it is popular, and they avoided as much of the math and homework as possible. And most of them are done with it.
