This set of flash cards is a collection of 28 game design principles that I’ve assembled over the years to help when creating a game. What I’m most proud of with this set is that in addition to the tips being quite useful – it is the organization of the principles that is notable. I’ve been able to order the principles into a 3 Word Acronym: G.A.M.E. P.R.I.N.C.I.P.L.E. R.E.C.O.M.M.E.N.D.A.T.I.O.N.S. This creates a mnemonic device to aid in recollection of all 28 principles.
