Finding the Perfect Family Game

kowalski1971 writes "Some poor soul with far too much time on his hands has decided - in an attempt to increase sales at his toyshop - to calculate the formula for the perfect family game. Apparently it is, 0.22a + 0.17f + 0.153n + (0.12c - 0.1g) + 0.1s + 0.09e + 0.06d + 0.054l + 0.05m + 0.011c = pfg ...and which game came out top? Cards. So much for the increased sales then."
