The endowment effect is cleverly implemented through character investment systems that make player creations feel personally significant. As players spend time developing their characters and acquiring rare items, they become psychologically invested in their creations. Path of Exile 2 enhances this through its legacy system, where players' choices create truly unique characters and item combinations that feel personally meaningful and difficult to abandon.Goal-setting theory is expertly applied through the Atlas endgame system, which provides clear, achievable objectives with appropriate rewards. Players can set both short-term goals like completing specific maps and long-term aspirations like defeating uber bosses. This structured progression gives purpose to the endgame while allowing players to choose paths that match their personal preferences and playstyles, maintaining motivation through clear direction and meaningful milestones.
