Games will be 750 points as this should allow players who aren't very familiar with the rules to have plenty of time for games and isn't too imposing for getting an army painted.
Players will need a 750 point list picked from either the core rulebook or one of the 'Armies of ....' supplements. (please be aware of the typos in the core rulebook. Check here for errata and FAQs.) If using one of the supplement rulebooks, you are free to use any of the Theatre Selectors as you see fit. Bear in mind that if you bring an early war list and your opponent brings a late war list then the games might not be 100% balanced. (Those German 88's are going to make a big dent in your Tankettes).
Forces picked from a British and Commonwealth, United States, Soviet Union or France and the Allies list will be on the Allied side. Forces picked from a Germany, Imperial Japan or Italy and the Axis will be on the Axis side.
No Armoured Platoons.
No Heavy or Super-Heavy tanks please. It will be VERY difficult for anyone with an early list to kill them. That said, everyone should probably bring some form of Anti-tank weaponry. This is about playing fun games not running Tiger 2's over Polish cavalry.
If you have an army with a variable national ability (such as the Armies of Great Britain), please use the same ability all day.
Players will need all of the usual assortment of dice and measures etc. Players will need to provide their own Order Dice and have something that they can use as Pin Markers (counters, chits, different coloured dice etc). Army lists should be available for your opponents to read, so please make sure they are clear and legible. No shorthand.
Models should, ideally, be painted (because it looks nicer that way) and it should be easy to determine what equipment each model has. E.g. Using a Panzer IV Ausf A as a Panzer IV Ausf B is fine. Using a Carden Lloyd as a Churchill probably isn't.

As always, feedback and comments below please.
