Galactic Harvester is no longer for sale on Steam. I have no idea if this game will work or not! I don't mean the key here, but rather the game itself. Who knows. Probably best for collectors and such.

That said, it's 2020 now, and keys are not as eternal as we once thought they were. Especially for withdrawn games Therefore, alas, I must say this:

This key is an old key. It was purchased some years ago. To the best of my knowledge, it's as fresh as it was the day it was bundle-bought. I haven't used it, and I haven't given it away. However, many developers revoke unused keys these days for no reason and without warning, so it's not possible to rely on keys the way we did once.

If the key doesn't work, please contact me. If I can fix the issue I certainly will.
