My issue with Pause Base is you can have a variation of someone playing pause all the time to another that never pauses. It makes balancing well not possible. It is also messy, especially in coop if you are constantly pausing, in the pause base games I've played, you also have issues where some PC's are faster at execution than others, so you never have a clear feeling of which PC is going to be able to execute next. It sound noble the idea, but imo it was never as clean as a true TB game.
I'm not sure you knew but Larian mentioned they wanted the Divine Divinities to be TB as well all along, it was the publisher that told them there is no market and make it real-time. It's a design choice and also reading Swen's forward in the manual he states he's always wanted to create a PnP experience on the PC, which is true turn and this game allowed him that dream.
