lost / acn both your ideas are pretty good, again, just not all that much of an improvement over what we have - acn your idea is pretty close to what they now have, except the 250 mile pressure point is now 190, the 500 pressure point you ask for is 360/370 and the 1000 pressure point is somewhere around 1400 miles (I have it written down somewhere), then there is another pressure point which generally only applies for internationals, somewhere around 2500.
lost, I agree with you on the tendancy to want to add sim city components to the simulation, I know madden football used to be a great bare bones simulation of games, but each season more add ons came on board, such that the simulation took a back seat to the 'stuff'. I 'm hoping that seble is not big into the 'stuff', although I am sure others are hoping just the opposite.
