Why is this hard? If they have ZERO value on waves 1 - 10, then set the game to a tie. Everyone cried so hard over cross. So many tears over building units together. Now that they're able to hold two lanes with COILER NONSENSE it's all good. It is the same as cross. The same. One player gets massive income while crippling one side of the team. At the time, I did not understand why there were so many tears, but it's not even close to fair anymore, because you don't have two other lanes to build income and push back against the cross at bottom.
