Yup. genlean, was many suggestions like Bar and web-mining... Intirely game was rebuilded) I think that main problems is:
1. Few players have too many planets for passive profit.
2. Few players have too many ships for mining asteroids (me too), which does not good.
*2. Problem not in SG1 or SG2, we lack of advertisements

May be genlean right and project have use those faucets "click the cow"?
*1. Should I explain? Find yourself in posts.
@genlean, fresh site on Galaxy is always good

@toecutter, is web-mining does good profit?
