I am playing in discovery from 4.84. I like to play here as the concept is very good and I like very much the way it is. But it can be better.
We have the armor upgrade for a long time which is hull multiplier. Now how about some Power core upgrade and shield booster on the same multiplier basis like armor. They will also take similar cargo space and so player can choose any of them at their best or all but in lower grade?
The upgrades can be purchased from any NPC base.
