Once the market becomes saturated with c3c and many more people have it, that is when they should probably merge. I wouldn't agree that the x pac is that much different from the real game to merit having its own forum permanently. If it was civ4, sure. But soon many people will have the game and this forum will start to absorb many of the c3c questions, as it already has started to. At that point, they might as well be brought together, as this forum should represent civ3 in it's current state, not how it was.
