If in pa would be an economic victory condition (metal stored), what would be in your oppinion the right amount? 500.000? Or something mapdependent like : amount of metalspots × 400?
Holding 75% of all metal spots would work on every map, and work independently of resource multipliers, though if you really are holding 75% of all metal then isn't it much more fun to swarm your opponent ?
We should also have a Space Victory for who makes it into orbit f- WAIT A MINUTE. What game was I playing again?
