“A game is a series of interesting decisions.”

Why it matters

Meier is here because his lessons are tools. Ask whether a mechanic produces an interesting decision and you have a way to cut half a design document. Ask how an outcome feels rather than what its probability is and you have a way to tune the other half. Few designers have handed the field two tests that simple and that durable.

   A game is a series of interesting decisions

   Meier's 1989 line became the field's shortest definition of play, and his 2012 talk unpacks what makes a decision interesting: real trade-offs, short-term against long-term, no dominant option, and enough information to choose but not enough to compute. Everything that is not a decision is either a reward or a chore. The test is still the first one a strategy designer applies to a new mechanic.

   Design for the player's psychology, not the math

   In his 2010 keynote Meier argued that gameplay is a psychological experience built on egomania and paranoia. Civilization went turn-based because real-time made players feel like observers rather than the star. Fair odds felt like cheating, so the displayed probabilities were bent toward what players believed. The lesson is to tune for how the outcome feels, then make the numbers agree.

   One third kept, one third improved, one third new

   Firaxis's rule for a sequel: a third of the game is what has to be there, a third is something tried before and now done better, a third is brand new. It keeps a long-running series from calcifying without alienating the players who carry it. Meier pairs it with a tuning habit: when a number is wrong, double it or halve it, because small nudges are invisible.
