I just wanted to pass kudos for the great exploration content you guys have put together. I do have a few suggestions:
1) More murder mystery episodes! I only got one of these once in the exploration chains and accidentally lost the quest waiting for my wife to arrive in the system to see if we could share the quest. I would definitely like to see more of these types of quests in general.
2) Faction memory! Have us explore new races and new civilizations and allow the game to remember faction ratings. Maybe one planet will trade special items with us based on our responses and interactions with their people/representatives over time.
3) And related to 2, negotiation episodes where our captains have to select responses to give in negotiation. The results will allow our captains to gain reputation with these civilizations and possibly affect trading opportunities in the future and open up new quests from the new civilization.
