Project Realism is primarily a set of systems for emergent gameplay. They form part of the core of larger games and may interface with combat, dialogue and all other systems important to gameplay. The purpose of these systems is to simulate the player character having realistic needs of food, water and rest in order to add depth, difficulty and realism to the game. Though they have ludonarrative value, they do not directly impact the main storyline of the game.
