Hi, if You'll like to create and build Your own spaceships and buildings in a persistent Space-Sandbox-MMO then I'll recommend to check out Dual Universe. The folks at MassivelOp did an interview with one of the developers about the current status of Alpha 2 and the future development. You can read the full interview here: Massivelop interview september 30th, 2019: https://massivelyop.com/2019/09/30/preview-dual-universe-demos-alpha-2s-player-economy-solar-system-and-space-stations/ Chris Roberts supports this project and also pledged during their kickstarter. Which is awesome in my opinion.
