Had the game for about a week. Got killed the first couple of times I played but this last "small" map I played worked well execpt I cannot seem to end the game. Everytime I think I've wiped out my enemy, he pops right back up somewhere else and continues to chip away at my planets. I got tired of trying to catch tiny fleets, which I always smash, and/or nuke system after system, but still the game doesn't end. What am I missing here? Why so much wiggle room at the end like this?
