Turn based combat can work better for party based games, and can be much more tactical than real time.
Wow, but that's a highly controversial statement! RTwP combat in BG 2 for example was awesome and it was a party based game.
I agree that turn-based combat is even more tactical but RTwP has a more fluid and immersive gameplay. It's simply a decision which path you want to follow but there is no rule like "party based game = turn-based combat works better".
I like the turn-based approach in D:OS because we don't have much of these games today and I always support variety. Project Eternity will have RTwP combat, D:OS will have turn-based combat and it's not even decided for Torment which combat system will be implemented. So I think there will be at least one game and hopefully more than one for every old-school RPG fan.
