What’s the difference between ARGs and Live-Action Roleplaying (LARP)?
The answer to this question is similar to the answer about Virtual Worlds. LARP participants gather in a real-world environment, but for the purpose of escaping the real world and entirely inhabiting a fantastic environment and play space. Players essentially leave the real world to participate in a LARP, where ARG players don’t leave their everyday life, instead their everyday life is altered.
