Well, I would call that a modification, definitely, Goblin. Modifying scenarios is easy but must be done with care.

SImply copy them into a temp file, rename them as scenxxx, do what you want in the editor, then rename them their campaign name and put them back into the campaigns folder.

If you really like experimenting, this can be interesting. Of course you have your original zip or installer file should something go awry and you can always restore files.

You oughta do some campaigns yourself, my friend. A lot of work, but a lot of fun.
