Real-world currency

When referring to money, the term real-world currency may arise. This unambiguously refers to currency that exists in reality, such as dollars, euros, or pounds, as opposed to a fictional currency used within the game in which these players are communicating.

Real-world currency is a relatively universal term for such a concept, but many other phrases exist which mean the same thing. Meatspace money, cold hard cash, digital dollars, and my landlord will take this are also commonly used to refer to money in the real-world. Such phrases are often used to reduce ambiguity when discussing payment for specialised user services, most notably art, but might be applicable in other scenarios such as when discussing the purchase of crystals.
