First off, thanks for the continued support for FFH2! My friend and I always play with Advanced Tactics enabled (mostly for the great generals, it feels wrong without them in the game). Some questions: 1. Tech diffusion... what impacts it? I understand that you get beakers towards techs that are already researched by others but does it require trade routes? Embassies? Not being at war? I'd love to understand the factors at play. 2. PoW exchange. Does accepting this have any actual impact on the game other than a diplo bonus? Do you return units you captured using a Command promo or Domination? Also I think the AI is way too aggressive about asking for this. They ask almost EVERY turn after a war, so eventually I just give in and accept it out of annoyance. 3. Non-aggression pact. Does this have any actual effect other than the +1 diplo bonus? My friend signed one of these with the Svartalfar and they declared on him two or three turns later. Not really out of character for Viconia, but maybe it ought to act like a peace treaty while active? One last misc. thing - I love the 'Cease bothering us!' option in singleplayer (although I think it needs a diplo penalty). Any chance of enabling this for multiplayer games?
