I havent played in a while, but with Diplomacy being released I was tempted to buy it and relive the glory day s of old. One thing kept me back: The pathetic tenancy of the AI to run away like a little girl any time the prospect of a moderate fight looked imminent. Does the AI updates in Diplomacy address this?
Sometimes it makes strategic sense to run off. The Diplomacy expansion offers two new AI difficulties, Cruel AI which has a 4x eco cheat and Vicious AI which has a 6x eco cheat.
Of course, if a macho guy like yourself wants opponents that aren't wimps, there's always online multiplayer against real human opponents. Human players don't get any eco buffs, but unlike the AI, they're capable of real strategic and tactical thought, so they don't go into the game with one hand tied behind their backs. If you do get the Diplomacy expansion, come try a 5v5 game sometime. You might like playing with people better than AI.
