This absolutely thrilled me. Right up until I realized that there's a closed-source, binary-only dependency (FBX SDK). I guess my dreams of playing this game (which I do, in fact, already own a copy of - twice over, actually) on Linux/aarch64 are still a ways off. AutoDesk indicated as of ~2017 that Linux/ARM support for the FBX SDK wasn't on their road map, and nothing seems to have changed since then.

Still- major kudos to Frictional for doing this. It's 100% an appreciated move, and very much in the right direction. The choice of FBX SDK is just, in hindsight, unfortunate, but that doesn't diminish the helpful nature of what they've done here.

(fingers crossed - maybe FBX SDK is just needed for the editor? Hope springs eternal...)
