I just picked up Avorion after watching so many folks play it and thinking it wasn't my kinda game I find myself really enjoying it! Building ships surprisingly simple even for a garbage builder like me. I really like seeing my ship(s) (you can build a fleet!) evolve over time and the building system is very intuitive! If Empyrion is Minecraft+No Man's Sky then Avorion would probably be Minecraft+X series or Eve.
