Yet Diablo III's Development Team, Community Managers, and other personnel are all still working to make this game more fun, with more content, and more awesome loot. They've already made many good changes to the game, and more continues to come - all for the original price.
"Well, how are they able to keep putting through updates?" Because of the RMAH. You may hate it. That's okay. Don't use it. But many people do. Some people have more time than money, others have more money than time. It bridges the gap between the hardcore player and the family / career person. And it doesn't matter if you like it or not since it's here to stay.
With all that said, I'd like to thank Diablo III's Development Team, Community Managers, and other personnel for making a wonderfully addictive game. I'm sure I'm not the only one looking forward to all the changes in the future.
