This particular "missing feature" doesn't worry me much, no. Trade routes as implemented in Civ IV seemed really random and hard to quantify; the player had no control over which routes were chosen. When it came time to decide whether it was a good idea to switch to Mercantilism (which eliminated foreign routes), the player had no in-game metric to determine whether this was a good idea or not, other than actually doing it. This is one case where I'd prefer a simpler mechanic if that means actually getting player control over it.I know you have been quite helpful around here, spending time carefully on what will be the features of this game piece by piece, but doesn't this worry you?
