wont start playing again until after last exam in early december, but after that... I'll be back!
we'll have to take a look at how the technical stuff sorts out, I noticed that if using directx 9 instead of 10/11 the game is much faster on my aging comp, so that would possibly make a simultaneous turns thing possible.
I will not miss religion too much.
Stacked combat? you mean non-stacked combat? and yes, I am loving the strategic possibilities and the new combat system!
city states should be in, but not too many, the default setting seems to be 2 CS per civ.
