Its a old PC RPG from back in 2000, I noticed it seemed absent on GOG and figured I mention about the game to see if can be obtained at some point in the future.

Yes, it's a good game and would be right at home here. There is a thread about it (which started in 2014 and still garners interest into 2019) which also goes into details as to why it might not show up at GOG. A shame.

I have the original Siege of Avalon anthology, 6 complete chapters. Boxed. Bought years ago from Electronics Boutique. Give me a secure address, that you don't mind anyone seeing, and it's yours.

I'm alright; I actually have the physical game itself and have played a little bit of it.

Just didn't have time to fully invest into it when I first played it.

There are several wishlist entries for the game. You could go ahead and add your vote to one or all of them. :)

I've heard of this one. It's one of the rare commercial games with a full source code release.

These were extremely interesting to me before Steam changed the whole Linux gaming scene.

Oh yes! This game was really RPG heavy compared to what is out there, and the combat was very different in terms of when it happened.
