frog, I'd say stick with every campaign, no matter how easy it may appear to be at the start. I thought my Alemanni campaign (VH/H) was a going to be a breeze after I raced to controlling 10+ of the WRE's settlements without much in the way of resistance. The nice thing about BI is a horde faction can really spice things up and the domino effect can cause havoc...

What then happened was a Goth horde moved through my lands and settled in the two WRE settlements on the very West and North of nowadays France. They were at war with the WRE so I thought no bother. However, their Westernmost settlement proceeded to rebel and all of a sudden the Ostrogoths appeared! Hmm, not good news, and so it proved to be... The same settlement rebelled again, this time returning to the WRE, and now I have a huge horde of Ostrogoths on my doorstep. They then proceeded to sack the 1 remaining Goth settlement thereby creating yet another horde!

Now I have 2 hordes in my lands, of which the Ostrogoths have just laid siege to my poorly defended capital. That's where I stand at the moment, with my once proud 10+ settlement empire now looking incredibly fragile...
