Does Trade alliance only preclude Trade/Research alliances, as I think it does? What's the reason for this rule? It seems that any alliance could serve any player's advantage. Knowing that you could ally with someone who will certainly sell you out (according the game's rules) is a risk you may have to consider worth taking. I would be more inclined to allow any alliances at all, but perhaps there are reasons for gameplay why we are doing this.
