This needs to be at the top. Starforged is amazing, because Ironsworn is an amazing system. All the influences you mentioned in starting post are also mentioned as influences for the making of Starforged. The only problem I see, is that your focus on mechanical system for the ship stuff.

Ptba is inherently not as mechanical as other meta systems. But I highly recommend checking it out.

Second suggestion would be Stars without Numbers, Crawford is praised for almost every release he does. You can’t go wrong for Sci Fi with his system, it offers quite more crunch than Starforged (from my knowledge, I didn’t read or play SWN myself!). But it offers, similar to Starforged, amazing tools for building worlds in a scifi setting, which can be used in any other system you might prefer.

Everything on my shelf. Cyborg, Forbidden Lands, Spire etc.

Is this satire? They would’ve to use mastodon.
