Excuse me guys.

When I install Kingdom, do I have to install all 4 campaign?

Can I just install 1 campaign, and will mods works if that happens?

Thanks guys.

it depends what units the mod uses eg if it uses Teutonic units u need that campaign installed to be honest the best idea is to install them all.

Actually, from my modding experience, if a mod ports units from one of the campaigns to the GC, for example, then you don't need the campaigns at all. If it's a mod for one of the campaigns, however, then obviously you need to install it.

Surgeon is right, I constantly play custom battles with factions that do not pertain to the campaign i'm on with no problems whatsoever. Just make sure you have MTW II installed. I personally, only had america's downloaded at first, and decided to install the rest when i had finished it.
