Well like I said, there are a lot of alternative games out there that are suited to a more casual crowd. It's good that developers still make games like Kingdom Come and Baldur's Gate to provide for players looking for more depth, immersive and engaging content.
Also, turn-based games are timeless, just like many other genres that have been around for 30+ years. I know a bunch of people that would never touched these kind of games and got completely hooked on BG3 anyway. Even myself that was never really into these kind of RPGs and tried Divinity games before, BG3 was absolutely stellar. It's one of those games that set a new standard many others could learn from these days.
