because as everyone knows Vikings just hate sheep
I did not know that and my great grand grand... grandfather was a Viking Well you learn something new everyday

but loses points when he kills innocent civilians
That doesn't sound Vikingish. Being punished for doing what a Viking does best, killing

I must agree with the other that it's a bold move to change game in the middle of the competition (perhaps not exactly in the middle of the competition).

However I must say I like this new idea. Especially since it involves a Viking So you better finish this game so that I can go on a Sheep killing spree
