I have played all 11 thanks to my Chinese heritage, although I have only play VI and VIII briefly. The Romance series is definitely action-less pure strategy. If you have iphone or ipad you should definitely give ROTTK II a go to see if it is your thing. It can't hurt to start as far back in the series as you can as the game just evolved to become more complicated through the series.

Dynasty Tactics are also actionless strategy, but much more focused on winning battle through complicated puzzle-like designs of combos than on running and building an empire.
