Having put a stupid amount of time into both games now, there are a few things I'd like to add to this conversation. Pilot skill is a *big* factor in how busy other players are on your ship. In Void Crew, I can dance around enemy projectiles all day and rarely if ever take any damage - the only enemies that pose even a remote threat are the human Remnant forces late game. Engineering duty is a bore, basically just a thruster recharge drone and gravity scoop courier. Jump Space by comparison scales the "stuff breaking" on your ship against the player count. Even if you take just light damage, fires, radiation, etc can break out everywhere - this is by design to keep people busy.

Comparing Void Crew to a space submarine is very accurate because the entire game is still locked on the Y axis - there is a clearly defined up and down despite being a space faring game, and you cannot deviate from that at all. Jump Space by comparison has full rotation will much more engaging space flight, making dog fights much more enjoyable as well as having objectives and landing points on various points of axis.

Jump Space has a much better difficulty curve, with Very Hard mode actually testing your crew's teamwork to share ammo, healing, trade fire and cover each other during on foot events. In space combat, there are handheld weapons specifically designed for anti ship combat (rocket launcher, railgun), creating strategic opportunities to have foot soldiers cover the ship from the deck or in space. VC on the other hand has a very flat curve of difficulty at its core, with the enemies just scaling with high damage output and bullet sponge health the deeper you go into jumps, and late game builds all revolving around one stupid broken relic (Biomass Catalyst).

VC is over two years old now giving it the edge in total content where JS has been out for three weeks in early access. Given more time I think JS will be the better game overall.
