First off, Lots of Great ideas on here and hope to see them in the game. I like the NPC Planet type the most. It could be linked to the Drannik Automatons since they are replicating themselves. But unknow to most is that they built these NPC type planets similar to death star. That can attack and defend itself. Its got like 100,000 hull and shields of 50,000. Attack of 10,000 to 20,000 and defense of 5,000 to 10,000. It drops artifacts that can help create some of these Eden, Dream and Rouge planets suggested on here. It would have to have a time limit of 3 days and 7 days max. Allowing for 10 to 20 players to get something out of it. That is just my thoughts on the NPC planet type.
