Setting idea: ancient gargantuan self maintaining, self building ship, original purpose is unknown, it has long (perhaps from its inception) been inhabited by various biological lifeforms, through millions of years of evolution various ecosystems exist. Where the AI has adjusted to coexist with the biological systems, often in symbiosis.
I like to imagine the sort of lifeforms and relationships that could exist.
I've been thinking about rpg systems to play this. I like the idea of using Mini Six, the author seems on point.
@hedgepig So ... Metamorphosis Alpha.

When it comes to picking mechanics, you have to really figure out what it is that you want to portray first and foremost. I would probably use #Starforged (or even raw #Ironsworn , depending on how I envisioned the internals of the ship).
One of the places to start is "do you ever expect the PCs to leave the ship?"
