The good news is there's a couple of decades where games in this style WERE real-time for the most part. A majority of players seem to like turn based a lot more, but neverwinter nights and the earlier baldurs gates have a pause-assign actions-unpause flow rather than turns.

With pen and paper d&d, guidebooks explain that turns represent about six seconds of action. Some of the older titles took this seriously and it makes trying to use mages in small parties absolutely insufferable, especially at early levels with a low concentration skill total.

Hilariously, this is one of the VERY FEW genre where I find I do prefer turn-based personally. I didn't turn on ATB mode in ff15, I refused to use strategic view and pausing in dragon age, but for CRPG I've found solidly defined turns to really help drive my decisionmaking.
