So here is my idea:
Era should open up a "Player Business". My vision for this shop would be that players can request for a business tag from the server (a set number of players will be aloud a tag at any time) where he/she can mine (weapon shops), or stock the shop within a time period to keep slots open for other people. For every mineral mined/ product stocked and turned into a mineral bin, they would earn money based on what is submitted.
Now since this shop has a limited stock. for the items sold would have a tempary set price which would be the min. As the stock decreases, the price of the item increases.
Anyways, post positive critism/comments.
