Well, we added a sort of railroad movement as a technological improvement – my game group has striven to avoid actually changing the rules outside of the tech tree.
BUT… I had an idea. The problem with the game seems to be, like hinted at above, is that the game drags on because of the slow movement. Germany can get into France no problem, but once the front line troops are some 4 or 5 spaces away from Berlin, well, the tide will turn because France and Britain are only 1 to 2 spaces from the front. The idea here, maybe someone can expand upon it, is to have a “strategic movement phase”.
I haven’t figured out where it would fit in, but initially I think it would happen just before the normal movement. Basically, and this is more to do with the time scale than it does with the railroads, but perhaps a nation can move all of their ground and air units as far as possible, any number of continuous spaces, as long as they are controlled by them and they do not move through, into or out of contested territories. So basically, they can reposition all their forces just behind the contested front line areas. Then when their movement phase starts, they then make their normal moves (moving into or out of contested territories for example, or moving into enemy territories to make them contested).
If nothing else I think it would speed up the game. I am playing a game at the moment and we are on turn 8 (at about 1.5 hours per turn) and it doesn’t seem like there is an end in sight any time soon. Just an idea.
