Had a Similar Idea but instead of Player-Housing I thought a Clan-Social space would be cool. [u]Ketch-Events[/u] Lets say 5 clan-mates are in the Ketch and suddenly the alarms start up, it's vex boarding the Ketch and it's up to the clan-mates to rid of them. [u]Upgrades[/u] You could earn them from completing Clan-Challenges and/or repelling "Ketch Attacks", these could provide visual/physical upgrades which make the ship look cooler and deadlier. You can even supply a "force" section which takes the amount of troops you have converts them to power and you need power to do the challenges. Low Power = Low Challenge = Low-End Reward High Power = Higher Challenge = High-End Reward
