I've done some reading about gruesome tales of folks spending hundreds of thousands of dollars on video game currencies only to have their accounts irreversibly stolen or lost due to a bad in game scam/trade, but are unable to take legal action because virtual currencies are not considered legal entities. Take for instance Warframe's platinum currency, Rockstar's virtual dollar or league of legend's Riot Points. Legally speaking, these "in game currencies" aren't recognized as personal property. But that doesn't change the fact that people place real dollar values on 60,000 Platinum or 50,000 riot points.
Now, I have to be guy to push this grey boundary. Suppose a stranger and I signed a contract in the real world (suppose the United States in a state of your choice) stating I'd pay him some in game currency for some real life service. If we ignore the EULA, TOS situation, if I received this real life service and refused to pay the in game currency would I be in legal trouble?
As per usual, not considering scamming anyone I'm just a curious guy.
