Excerpt: "Most of Act I is familiar territory for those like me who played the Beta. Nothing has changed there except the inclusion of achievements. I had a couple of friends online playing, but decidedly chose to play solo to not incur any unnecessary disconnects, issues, or lag. If you didn’t know, Diablo III uses an “always-on” DRM system that has left many fans angry. And the issues that were present all related to login to Battle.net and could have been avoided if singleplayer didn’t require it. Even when you’re playing the campaign solo, you have a latency to the server and could leave your game open for people to jump in."
