The business of gaming is definitely not always what it's cracked up to be. There are tons of mundane chores to see to everyday to make sure that your game keeps running and your customers don't go crazy.
First, the financial side of things can be extremely time consuming when you're dealing with 10 different methods of paying. Honestly, I can sometimes see why MMOs just decide to go the monthly fee and that's it. Anything that isn't hard-coded just simply isn't offered by them. Two to three hours a day, easily, can be eaten up by dealing with player transactions. Then you have players who request to purchase something that you do not sell. Then you evaluate whether or not you can sell them what they want. It just mires a lot of things down.
I wish I could say that running a game is all about game development, creativity, and expansive plotlines. Unfortunately, tons of stuff have to be done in the day-to-day running of things before we can even start on all that fun stuff.
