Well... I had thought of artifacts and random events... And I wanted to incorporate them, but I wanted to get the game going smoothly first Okay, so here are answers to the previous things.
Maybe corners should be no good. I made the corners rule because I'm actually planning on running another version of this game sometime soon, except on another world with a map that has instead of the 39 territories that this one does, the other one has 150 something. So how about no corners for this game.
Next... I think artifacts would be great fun, and so would weather... but things may just be a bit too complicated for right now. I think I will think of artifact effects and random events and stuff like that for later, but not incorporate them until I'm convinced that the game is running so smoothly that I won't blast the order of things to mars by introducing yet another new rule.
Another thing... this game is not supposed to be the exact same history as the Great War in myth. It's a parallel universe, so to speak, but may have completely different outcomes... just a bit of fun thought. Okay I'll stop ranting now.
Okay, so here are answers to the previous things.
