I played BG1 but didn't get very far into it, and one of the reasons was the RTWP. Now maybe if I had persevered longer and gotten to understand it better, it might be different, but I don't like it and would certainly not have bought BG3 if it had not been turnbased. That said I understand the reasoning behind switching to some kind of auto-mode for "easy" battles. On the other hand you would have to do all kinds of strategy setups, e.g. to prevent your lvl 5 wizard from expending his only fireball slot on a group of spiders. (I know you set up some priorities for several actions for every character in BG1, but I never got as far as Lvl5 characters, so not sure how you would protect spell slots from being used unnecessarily)
