This is a game that will get rediscovered for several more years I think. But ue to the intricate quirks of modding, it might not see a lot of new modding.
But Sins has one other use that I don't hear anyone mentioning: Say you're an aspiring scfi author or artist. You need a cover or web art for your project with custom ships, etc.
Pop a mesh model into Sins, stage the shot with your own backgrounds and you have budget space art creation. Way cheaper than hiring a professional to create it for you from scratch.
