1. What is artifact research? Its on the empire tab in the end game results, and despite having found all but one artifact in one game after exploring every planet (must you have all 9 to conduct it?) and researching EVERYTHING, I've yet to see anyone, human or computer player, get even a single point in this.
2. When traversing between solar systems, can people end up anywhere, or do they just end up at either a sun or a wormhole? I'm trying to work out where I should put my major defenses in massive multi-system games, and I've yet to see people pop up anywhere else.
