Turn base is a better game IMO. Sim sounds good but practice its nothing more then timed RT. I like to look and plan and check all my stuff and not be rushed because its "easier" I want the best gaming experence not the fastest/easiest. Maybe an option would be either Sim or TB. Like Civ. I am a old school TB guy anything else just doesnt cut it. Thats really the main reason i bought this game . I was looking to get back the roots ie: Kings Bounty/MOM. What ever they decide i know it will be good, these guys are working hard and giving it all they got, i give them credit for standing up and takin some shots and then trying to retool to make the game the best it can be.
Simultaneous turns pretty much become a requirement as you add more people. With two players you spend 50% of the time in classic turns doing nothing. With 4 players, you spend 75% of the time doing nothing. With 8 players... well nobody would ever play an 8 player game under that rule set, so it doesn't matter. 
Properly implemented simultaneous turns are nothing like realtime, and there's no reason for you to be rushed. Turn time limits are a seperate thing entirely.
