Since the mod itself is likely never going to be ported, and the original project has such wonky licensing restrictions, what is the end goal of keeping the assets available?

I don't mean this in a "why even bother" way, I genuinely want to understand the purpose of doing this.

There is no goal, other than a different appearance, at least for some. But I use them to add my own content to my games. I play a unique Facrtorio that no one else plays, with mods that I will likely never publish. I expect there are others that are capable of modding their own content too, and like me, have only basic graphics capabilities. Having access to the IR3 assets can go a long way to making your own content look nice.

Hi there, are you aware of the IR3 Patchset? I've realised that it doesn't come up if you just search "IR3" so I'm going to address this.

0n0w1c, could I ask you to link to the Patchset, and I'll do the same for you?

It is done.
