Scorched Earth offers a whole new strategy where Supply Centers can be destroyed before they fall in your enemy's hands.

This adds another level of anticipation.
For the attacker: rushing in too late and you'll find that the SC is on fire and lost forever. A defender may choose to set fire to its SCs if it feels threatened and desparate about its chances of survival. Beleagering an enemy may not be the best strategy.
For the defender: destroy the SC you're occupying too early and you loose the extra unit; hesitate too long and your chances of destroying it may be gone.

Viking rules state that a Solo victory requires a minimum of 26 SCs.
One player has argued that "in theory a player could be deprived of a solo due to reasons having nothing to do with his skill." and suggested "a vote that 26 wins, or 50% of the total."

My opinion as a GM is that Scorched Earth requires more from the Diplomatic Skills to prevent that no 26 SC are left for a Solo. Sooth the other players' into trusting you, team up with other players, avoid brute-force, etcetera. Subtlety is key here.

That it is possible to win by a Solo was shown in the previous Viking game.

But since this is YOUR game, I would like you - the players - to decide.
Let the voting begin...
