Astriarch Multiplayer 1.4.0 has just been published to the beta.astriarch.com site. This version adds a major new feature: Trading. From any owned planet a player can open the trading interface that allows for trading resources with the Galactic Bank. Players can buy or sell food, ore, and iridium for gold, the prices are determined by the resource amount in the trading center stockpile.
The UI for the Trading Center is a bit rough and there are plans to improve on the usability and the aesthetics but we wanted to release the feature for feedback and testing. There may also be some balancing required on the pricing model to make sure it's not too easy to get gold by just farming like crazy and then selling as much food as possible.
