That's a good way of doing it. Just made a mod pack out of it but my main campaign never came with it lol. Not a hard fix from this point onwards. Thanks for assisting and without a doubt you would've helped many more who read your comments. Cheers
EDIT: Still not working for me. Even when I uncheck all of the other campaign and only have my main_rome campaign selected, it will still put in prologue 2 and 3 in only. There needs to be a proper guide for it because this is not easy to do.
