From a business standpoint,Diablo is essentially a cookie-clicking game. Aside from maybe choosing a skill tree, there isn't really any skill involved, you simply run at things and click like a madmad until you get that "ding". It's perfect for mobile gaming, and surprising this didn't happen earlier. It will no doubt be hugely popular.
Are fans correct to be outraged or this is just another embarrassing moment (one of many) in gaming?
