it seems this already exists as arg

the metagame is played by a group of people

all the metagame necessarily needs is a flipover and a working permanent marker with the following text written on it:

RULE 1: all rules on this flipover are in force

when starting the metagame it can be efficient to answer one or both of the following questions

• TYPE: what type of game do you want to play?
  • you could eg choose from this list:
  • role play
  • board game
• PURPOSE: what is the purpose of the game? or more precisely: what do you want to model, like:
  • power balance
  • efficiency in taking decisions

when evaluating it can be of interest to answer the following questions

• which rules stayed implicit?
• in particular: did the following rule appear on the flipover:

RULE [some number]: RULE 1 is in force

whenever you have played a game please email your results to me including

• answers to the TYPE and PURPOSE questions (if any)
• (a photograph of) the flipover(s) with the rules that came into force

instead of beginning "from scratch" you can also start from a readymade ruleset. shortly a list of standard rulesets will be available (with the help of your feedback).
