One odd discrepancy that came to mind, though. If you recall the IGN interview with Barry Caudhill, he mentioned that trade routes will form automatically after you sign a 'trade agreement' with another nation. Yet, in the E3 video, we see Soren making a specific trade of corn for wheat in the diplomacy screen
! So, which is it-do you still negotiate individual trade agreements, or do you sign an all-encompassing 'trade agreement' which allows for trade routes to start forming naturally? Or, perhaps its a combination of the two?? Guess we will have to wait and see!
