As Diablo 3 fans take advantage of the invite only beta, many have encountered errors and many bugs that are sure to drive most people wild. The problems only increased when many more people eagerly rushed to the gates to try and test and play the game. The players themselves would have to undergo the download procedure which would take a long while for some, as it was a very large download. After having successfully installed the files, the launch players would refuse to work correctly and for those who were lucky enough to have the launch player work correctly were met with resistance when an error message would be displayed. These were just some of the annoying obstacles encountered. The players who were doing Blizzard a favor and stress testing the game, would report their concerns and complaints to the Battle Net forums. While many may be frustrated by all these errors and problems that occurred, its very important to remember that the purpose of this open beta period is to serve as a stress test that ensures the end product will stand up to the harsh demands of its players. Blizzard is doing its best to provide its fans with the best game everyone has been craving ever since the preconception of Diablo 3.
