Here is another of the optional rules for MEP, which I air for public criticism before incorporating into the draft (probably next weekend, all being well).
Blinds provide an interesting element of "Fog of War" - highly recommended. My solo game has an option where you can shuffle the identity of the blinds for one or both armies, so that one or both commanders has/have no idea who or what is arriving when - that is a decent working definition of chaos. Probably takes the idea a little too far, though it can generate some furious fun.
This draft rule will be identifiable as heavily influenced by TooFatLardies - but who else am I going to borrow ideas on Blinds from?
