By the gods ! I miss them all !
Just the old warscape city I don't care. Can we call them cities anyway ? RTW and M2TW had real cities on the opposite.
In my eyes the most important are the old trait system and the old building system. Both could use some innovations of course, I am not a brainless reactionary, but they makes more interesting bases to work with. Family Tree and Moving capital are very nice details. I don't understand why both were removed.
The new ability direction makes me doubt about TW future through. Flaming arrows for horse archer and flaming javelins for every javeliners is a no way for me and will probably keep me away form any complete vanilla experience as long as they will stay.
I am going to add Pre-Empire IU and pre Shogun 2 portrait. The first was far more easier to use and add to the game atmosphere while the second was just as good as the in-game portrait but is less gourmand performance wise.
