Over the course of many games, players develop rules of thumb to automate low-level decision-making, allowing them to execute more sophisticated strategies. The process of learning and testing heuristics, or "climbing the heuristic tree," is a major factor in what makes games fun and replayable.

Complex games live or die by how well they onboard players. Among other things, this means making sure new players have simple tactics they can latch onto before they understand the game, also
