In AOE2 wall construction is a click and drag process but it is very .. "square" or .. stuck on a grid like.. In AOM you can more freely place where you want the walls and they aren't necessarily on right angles to each other.
Will wall construction be more like AOE2 or AOM? and Will units be able to get on the walls? I always wished that you could in AOE2 and AOM but alas they didn't do it.
In AOE 2 gathering resources was a big factor. I loved it. How important will it be in 0 A.D.? On a scale of 1-10 how important will it be? Also... what kind of resources will be gathered?
