Why not add inflatable space habitats and inflatable heatshields? They could be procedural like everything else.
That along with the ability to change the Oxidizer/fuel ratio and see the effects of stoichiometric combustion in game.
A few other ideas: Caves and procedural points of interest on every body. Make the career almost entirely procedural. Start in a procedural system on a procedural habitable planet, to explore your procedural system.
Make checkpoints procedural. Make EVERYTHING PROCEDURAL EXCEPT THE CAREER TECH TREE PROGRESS.
Give us parts that can generate TP so players can compare theirs to their friends.
Make astronauts become veterans/get promoted for every number of missions they do. You could have different unlocks for each droid, like resistance to damage or the ability to jump higher, maybe a faster jetpack? Who knows!
More space capsules would be pretty great too, you could even just make the Patriot capsule a style of the space capsules, same with the vroz modules. Then you could incorporate more capsules into the game.
So far the biggest limiting factor for me, is the capsules max radius or 2.5-3M when Artemis & even Apollo were bigger than that diameter by almost an entire meter!
@Toinkove omfg of course I was misunderstanding lol. While we are at it why not add decaying orbits like real life? Well damn. Sucks to know my favorite flight sim is essentially DOA since I just started playing a few months ago. Thanks for the useful info!
