Can someone please explain how I could use the -mod:(insert mod name here) command line to run Megas Alexandros. I don't want to overwrite any of the original rtw files. I made a copy of BI to mod as that is what I am creating Megas Alexandros off of. I can not seem to get it to work though. Can someone help me please? I have total war eras, so anything I need concerning the actual game I have, just tell me please.
