As far as I'm concerned a scenario is a map that has a fixed storyline with pre-designed gods and fixed nations and alliances. And some kind of unique thematic victory condition. Preferably there would be an intrigue unfolding during gameplay.

To it seems that Dom3 doesn't really support what I would call a "scenario" or "campaign" which I accossiate mostly with single player.

I guess that roleplayed multiplayer games like the one you mention could fill the gap to a degree. But who cares what words we use, call it what you will.

Edit: But no, I don't think you should post such games it in this forum. They very clearly belong in the multiplayer section, and only there.
