I don't know yet, @Stan`If they already made it as a mod and are ready to maintain them, it may work out better in the long-run. For me to update everybody's maps that already exist in the mod every time a new version of 0 A.D. is release might be too much at some point. But these are cool maps, indeed.  

I know you have OCD for formations,I just can't prove it that aside, this is a very smooth very nice movement of formations. I have a stigma against using formations mainly because of (obviously) that "dumb troops keep going ahead and die" bit also because the formations are feel so,so SO un-smooth this is also historically accurate,as one of the main points of wedge formation is that the one ahead will be the captain, and the ones behind simply need to follow his lead and move exactly as he does, therefore being almost instantaneous "command orders" of that era

I think we can look into the game Stronghold for some guidance or maybe ask them how they did it.

The prospect of bridges is great, but the prospect of walls you can walk on is awesome.

I didn't put much thought into it, honestly.
