I would like to see the implementation of allowing for temp portals to use oort to extend the time active. Still one way. this would allow a person to keep a portal to an exo world open for a few hours during harvesting runs. The cost? well 24 blinks is 9 shards per hour, 42 blinks be around what 16ish per hour?
Next idea to add in would be a machine that would give a galactic atlas, this would report exo planets about and what the close planet they are near.
last idea for now. A way to summon or spawn exoplanets in by players through some sort of summoning that would cost resources. this can offer alot of features, like forging can have features. forge up a exo summoning, used in a totem, make is really costly! perhaps even many players will need to activate, creating a summon counter.
