I've been watching a video of the E3 of the new Civilization and it appear that town does not have ultra high defence that prevent all early army to take town.
This is a very good news for the civ series because this was make no sense since civ5: Impossible to take town without a very big army. This was even imo, plain dumb and retarded.
So the rush will be back in MP and this is going to be a lot of fun. Defend your city and play well from the beginning to the end.
And I hear some rumours on the civfanatic forum that it could possible to build wall and have ranged attack town defence. I hope this defence is not going to be too good like in civ5 and Beyond Earth.
See you in the rush!
