I actually have a friend who used to be a game master, basically all you have to do all day is to stay logged into the game and liaise with the users. I remember he even managed the game's inventory items, basically he spends his life playing games. Salary i believe he earns around rm1400.

I quote this from WoW

The ideal candidate is a hardcore MMORPG player who is very organized, with excellent communication and customer service skills.
