Well, I've played several turn-based games, and I generally like them. Solasta, when it came out was the best, but the travel options and rest mode could have been better.
BG3 hit a home run with their camp scenario. That was pure genius.
One of the other shortcomings of Solasta was the limited battleground area setup. BG3 is much better, and I like that you can make camp anywhere, because that is reality. You are adventurers out in the wilderness, so you should be able to make a fire and drop your bedroll almost anywhere.
I like how BG3 has used the 5E rules, although I didn't really play 5E (I was long before that time) and I actually learned about 5E watching Critical Role.
I don't think BG3 will replace anything, as I still enjoy the Assassins Creed combat, still like Skyrim and the Witcher to this day, but the old D & D, turn-based combat, I love, and doing it on PC with the visuals is a Dungeon Master's dream.
Now I have played Divinity, but I'm here to tell you BG3 has that totally outclassed.
