How do I break the Roman-campaign addiction?

[overweightninja]

yeh, I already went there. The link is broken.

Isn't there a simpler way to get it working (copy edu files, etc) instead of downloading another 700 mb file and reinstalling?

Create a shortcut to your BI exe and add the mod switch to it ("-mod:EB"). Then copy paste the "imperial_campaign" folder from "\EB\Data\world\maps\campaign" and rename the copy to "barbarian_invasion".

They're may be more but that's all I remember for right now, I suggest you try Ferromancers mod again though, just checked the link is working fine now.
Cheers
