?After messing around with it, I found it's possible to change the trail.? The opponents are indeed hard coded like we talked about though. No way around that sadly. That said, you can change the map to whatever one would like. Also with the AIV editor I guess one could make anything interesting.? I used the 1st mission "Arrival" as a test. As long as you name any map the same as the one used in the title for the trail mission This works. "a new land" is the map used in Arrival. Once you change the name of your map to "A new land" you then put it in the "EUma" folder that comes with medieval England? then your done. Any map will do. I used the out of the box France map that came with medieval England in this case. ?Its interesting but I'm not sure how much time I have to invest in such a project alone. Plus considering the fact that you can't add or change the AI opponents it may be best to just enjoy the skirmish mode and forget about it.
