Popular Hidden Movement Board Games (Mechanic)

A Simplified Wargame was published in the Field Artillery Journal in 1922. It was designed as a simplified version of something like Kriegsspiel. And to a great extent it succeeds. I would say that the main differences is that there is no FoW, no unbounded movements (That is to say movement along a linear path that runs between "junctions") and it has no umpire.
The rulebook is set up in an interesting fashion. The reader is given no direct rules from the start and it launches into a scenario of how the game could play out. after about 5 pages of this it then gets down to the rules. The rules are not hard to comprehend. However while reading the rules I continually ran into spots where I could see the potential for loopholes. Maybe no loopholes, maybe more like a giant hole. For instance Miles (the author) has a rule that says "the maximum number of troops that can travel on the road is 25000. Does this apply to both sides (enemy and friendly) so that if I'm approaching the enemy from one side I actually can't do that because he's simultaneously approaching me on the same road.
It can be reasonably inferred that it does not but the fact that there is no concrete rule to pull out when you need it is frusterating and with a lot of them there are a lot of gray areas in the game.
The game removes hidden movement and replaces it with hidden troop strength and composition. Which works okay and with the ability to split forces into multiple other forces and transfer troops by having two units pass on a road does help to keep the idea of secrecy and not having all of the knowledge alive.
I think the game could have had more watertight rules and maybe because it was so simple I think additional rules could have been added.
There are a few things that I didn't really realize until I sat down and played it. The main benefit of Cavalry is that they can move quickly and then automatically transfer into infantry behind enemy lines. So if you can just make sure that you aren't attacked while in your cavalry form then you should be fine.
Artillery's main purpose is to increase the strength of you force. Because they can travel as quickly as cavalry they serve in the cavalry divisions well because it can bring the cavalry forces up to a reasonable strength. When coupled with infantry their main benefit is that instead of just being able to work with a max force strength of 25000 (if all your units were infantry) you'll have a capability of getting to 30000.
ON the whole it's inspired me to go make my own game. I would definitly play it again.
