Thanks for asking Ray
As Dave said, it is all going well and in some cases we are testing the mechanisms pretty much to destruction.
One thing is for sure.... there will be no need for a large PDF addenda!
The rules themselves are pretty straightforward.. a new player arrived after the game started yesterday and after about 3 hours had pretty much sussed most of the turn by turn mechanix. That was a very good sign.. he is not a Napoleonic player and in fact had never played the period before.
I think the rules will probably run well over 100 pages now. Most of the test is detailed explanations and examples to illustrate concepts. That text is now on its 18th revision. The additional notes generated by playtests are getting shorter and shorter now. We had cause to refer o the main body of text a few times yesterday but not too much. The ebb and flow of the game is very dramatic compared to a 'typical' rule set for the period.
My target is January or February but if you remember.... this is going in to the exact same cycle as BLB.. at this point on 06 I was planning for Jan/Feb 07. We released in April 07... that could be a good indicator!
