…nothing? Yes, that’s right. It doesn’t affect your score, it doesn’t impact timing windows, and it isn’t a leftover stand in for the oft-rumored “Jukebox mode.” It’s just an inside programming prank.
According to Rock Band 2 Senior Designer Dan Teasdale, “Awesomeness Detection” was somewhat of a last second addition to the Game Modifier menu by Dan prior to release of Rock Band 2. According to Teasdale:
“I think I spent two minutes putting it in, like just defining it in our code for modifiers…”
“Part of it was us being complete dicks! But the other half of it was seeing all the things people see placebos when they do all this stuff. It was amazing.”
Ha! I never thought much of it, because if it did do something, I’m sure I would have heard about it. I’ve typically stayed out of the modifier menu, unless I’m hosting a party… then I’ll turn on No Fail Mode. I’ve heard of people being obsessed with discovering it’s true meaning, and I have a feeling there were still be a few out there that refuse to accept this red herring, and will continue to explore this modifier.
