Thanks man, much appreciated feedback.
Re GAE. Yes it could be ported across but would need to change a lot in XML, mostly removing multiple animations and particles. It's a fair amount of work and I aren't volunteering to do it, but if anyone wants to that's cool by me.
To stop your units wandering off every time they attack use the "hold" command - most units have this (it's moddable in the xml).
Re Guns. Gunpowder was pretty central to Chinese military, so hard to remove all gunpowder units. But removing musketeers would be easy. To do so....
1) copy the faction folder and rename it so that you now have a second (cloned) faction
2) rename the faction xml file in the new faction folder to match the folder's name.
3) In the units folder of the new faction, go to the buildings which build units you want to remove and in the building xml remove the command to build them.
4) if the unit being removed can be morphed into, go to the unit that morphs and remove the morph command
5) test it by playing.
I have no problem with people modding my mods, just be nice about it
