This game is addictive for people that like to work with interacting systems. This engine design could put out more power, could be more fuel efficient, if I redesign this gun I can save space while taking a marginal hit to efficiency, if I change the hull I can take more hits while preserving bouyancy, etc.

Do beware that it'll take a few hours spent on each unique element to fully understand what makes it work and what doesn't. Start relatively small (20-30m) and you'll be building floating cities and nuking baddies from the penthouse on your latest spacestation in no-time.
