Ugggh, this is frustrating. We had two games in a row where we destroyed 3 out of 4 enemy buildings and had all of our standing, enemy started turtling heavily, killing anything that even got even remotely close to their last building. Then, when timelimit hits, they win by points gained.
I think timelimit winning condition should be whoever owns more buildings wins. And only if number of buildings is the same, take score into account.
