In Camelot Unchained, physics supports an overarching goal of unique player experiences. The dev team wants things to happen to players that may have never happened to any other player. That comes from chaos, but the problem with chaos is that it leads to players feeling like they're at the mercy of a cruel and whimsical higher power, rather than existing within a set of defined and understandable rules. That's where things like physics come into the picture. Camelot Unchained's physics system will create predictable actions (like bits of walls falling to pieces when they're bombarded), give them consequences (like those bits falling on the ground and potentially on players who are between the bits and the ground), and set them loose in the world to interact with other predictable systems. The result? A set of interconnected systems that make your game experience way cooler without torturing players with invisible dice rolls.
