THIS GAMBLING FOR EVERYTHING BULLCRAP NEEDS TO GO!!!!! ITS A FREAKING VIDEO GAME!!! NOT THE MEGAMILLIONS, not poker.... Its a beautiful fantasy world, not some freaking gambling hall run by a japanese mafia.
Recently, the Korean government ruled that if players were allowed to sell items that they obtained in game for real money, that this would constitute gambling. As such players would not be able to cash out sales from the RMT auction house in Diablo III from Korea.
Games, with their randomized rewards, do have one of the three elements required to meet the definition of gambling:
1. Real Money must be invested
2. The results must be determined by chance, not skill.
3. Real Money must be returned
Online games typically fall into the game of chance (vs game of skill) category. The user has limited control/knowledge over what the outcome will be. When a mob is killed, the player does not have a way to control what items they obtain (if any) as a result. This makes it a chance event, not a skill event.
