I was reading a post that suggest a way to cripple the AI research abilities. It says to trade luxuries and tech for gpt. I play in monarch lvl (which I have yet to win) and it is impossible to get any gpt. I could ask for 60 gold, lump sum and the civ would accept. I then ask for only 1 gpt and no lump sum, they say they will never accept such a deal. Isnt gpt based on 20 turns, if so thats only 20 gold!! this seems to only happen in the first 2 ages....after that i can get gpt....anybody???
