Are there currently any under consideration? If so, will Firaxis fix th trade issues in Civ3 that makes trade so stupidly unreal? I mean, in Civ2, you could trade all your resources like hides for example. In Civ3, you can only trade a portion of your resources - and none of them is livestock and other food based resources that produce other products. I demand more realisitc trade options in Civ3!
just to play devils advocate, in Civ2 you could trade commodities you just got from a city at one end of your empire and trade instantly with it an empire whose only contact with you had been a horseman at the other end of your empire! not very realistic!
