+1 to that.
While I'm on this subject, Neutron systems should be more Fun.
Neutron systems are something I totally avoid until I'm already over the shark and into Silly; in my current testing run, I hit them now that I'm flying around with Mark Zuckerberg's bank account and literally don't care, other than being mildly triggered by unmarked places on the map. They feel like pointlessly dangerous places, with practically no jackpots of interesting gameplay to enjoy, and all of the "fun" of maybe losing all of my Supplies if I jump in and didn't save first. If I ever played Iron Mode in Vanilla, I'd not bother unless past Omega and using some dreadfully-optimaxed fleet designed to just explore.
1. Neutron stars should never have inhabitable worlds, worlds with farmland etc., for obvious reasons. But they should generate unusual numbers of worlds for mining Transplutonics with a high probability of +3 production.
2. There should be some ultimate Domain gimmick mechanic whereby if Player has <MacGuffin> they can build something that surrounds a Neutron star with barriers in exchange for a ridiculous amount of Refined Metal, making these systems potentially actually useful.
3. It'd be Fun if there was a Hull Mod that allowed players to dip into Neutron Star streams and trade Supplies for Fuel in a real hurry. Something about harnessing all that energy in Nature's biggest particle accelerators or something.
4. It'd also be Fun if there was a Hull Mod that allowed players to "sail" with them, being pushed but safely, that allowed them to reach phenomenal velocities or something. IDK what fun could be had there, but it seems like there's an opportunity.
5. Neutron stars should have more than their fair share of Domain fleets / artefacts. Something about how the Von Neumann devices got fried by the constant exposure to neutrinos, and just stuck around in their default mode- replicating. I think it'd be pretty amusing to enter one of these Systems in search of treasure and possible danger ("Captain, we have a 1500-DP Domain drone fleet off the portside bow? Now what?" "Oh, never fear, me hearties, I've been saving up all my slow-kiting skillz for this, tee hee").
