BUT, the hands-down winner was clear once I had played Alpha Centauri. There you could tell unit A to go to location B and it would USE THE RAILWAY. I would really, really, like not having to take units along a railway one bit at a time - if you tell the units to go to destination X, then will set off in the most direct line, over mountains and swamps, even when you've got a railroad linking the source and destination. This causes more wasted time than any other feature in the game, and it applies to all units in all games. You can't even make them take a road. <gnash teeth>
