Wow, I thought everyone exaggerated Muse fans, but I come in here for the first time in forever, and DAMN, do you guys get butthurt when Harmonix makes another Muse joke.
"Why don't they just tell us?" Same reason they don't tell any details about any band?
"Why do they have an attitude?" They're poking fun. You're calling John D. an *******. Attitude or not, theirs is certainly better than yours.
"Big laugh at our expense." Are you one of the people constantly pressing for Muse even though they know the forum demand? If yes, stop. They know. Are you one of the more tame Muse fans? Then it's not directed at you to begin with.
