I was thinking to add a little more interest in the economic part of the game it might be a good idea to give a tourism income bonus for your civ if you control influence over areas of the map with pq0 planets that have intersting features on them(ie. rings more than one moon etc.)Simular to real life if your country has a natural wonder like the grand canyon, niagra falls or nice sandy beaches you'll have a lot of tourists visiting to see these sights.This would mean in terms of gameplay you may decide to set up an influence starbase near a cluster of otherwise meaningless pq0 planets just to draw extra tourism revenue.Let me know if you think this may be a good idea or maybe it will just complicate things.
