I am re-posting this as I still haven't managed to figure out which game is haunting my memory.
The game came on an early 2000's European PC game magazine demo disc. It could have been PCGamer, PCZone or a Finnish PC game magazine.
What I remember is something like this:
You start out in a nomadic camp in a desert. The game is either an action-adventure or an RPG (possibly a hybrid). You (a male protagonist, I believe) go around the camp talking to people and completing tasks. It has a fantasy/sci-fi like setting. You are preparing to leave the camp for some reason. One of the tasks involves getting a rudimentary weapon (a sword or a stick?). Once you have left the camp and entered the desert, the demo ends. It is a 3D game, and I *think* it's in the third-person. You can jump. I remember some strange, alien animals (although the people in the camp were all human as was the protagonist). Everything was a very tan brown, "desert" colour. The buildings looked like brown stone huts or tents.
This is all I can remember. I'm not even sure how much of it is accurate, and how much of it my mind has made up over the years.
I remember being impressed by the "freedom" it offered and the graphics.
I was easily impressed back then.
It is not Outcast, or Heavy Metal FAKK 2 (as some people have suggested).
Any suggestions will be greatly appreciated. I may also have a surprise gift for the person that manages to find the game for me?
