Creating a definition for the word “game” that doesn’t exclude things that are obviously games, or include things that are obviously not, is hard. It may be entirely impossible. Many individuals have tried and failed. No one has yet succeeded.
That would certainly qualify this as one of game design’s hardest problems. Perhaps if we bash enough of our brains together, we can find a better answer than any that has come before. Or at least move the needle slightly in the right direction.
