I love both Baldur's Gate III and fighting games but disagree. I think both are woefully inadequate at explaining their rules to players. Larian games need to not only make BGIII's rules as clear as a rulebook but also make tactics and strategies plain and clear to the user. Otherwise, it is very easy to fall back on decades of video game expectation only to realize your expectations are wrong. I had a co-op game of BG3 with a friend. My friend couldn't understand why he had to position his units anywhere. Didn't understand why inventory wasn't just immediately being teleported to a shared infinite item box. Didn't understand the basic mechanics of D&D combat (which even then, Larian changes to various degrees) Didn't understand why decisions had any meaningful consequences. Didn't even understand what he was supposed to be doing narratively despite there being a quest log and having us recap the story up to the point we were.
While fighting game tutorials have gotten better, I still have yet to experience one that explains very basic things that the FGC takes for granted. Things like health bars being identical physical lengths but representing different numerical values. Things like "waiting for your turn." Things like meter management.
Complex games are great. But complex games need to recognize that they have a larger duty to teach than simpler games. I think video game design needs to take a page out of tabletop game design and provide some analog to the tabletop rulebook: complete with not just rules but detailed explanations, sidebars, and examples of play.
