Emergent gameplay refers to complex situations in video games, board games, or role-playing games that emerge from the interaction of relatively simple game mechanics.[1]
Designers have attempted to encourage emergent play by providing tools to players such as placing web browsers within the game engine (such as in Eve Online, The Matrix Online), providing XML integration tools and programming languages (Second Life), fixing exchange rates (Entropia Universe), and allowing a player to spawn any object they desire to solve a puzzle (Scribblenauts).[citation needed]
