fear of failing out because, well ... they're just not that talented a wannabe rocker. And it turns out this casual-focused feature will be absent from Guitar Hero: World Tour.
But, the real question is: does the game need it? Certainly, other rhythm-based games sold extremely well without it, including past Guitar Hero games and the original Rock Band. Does this lack of a "No Fail" option tick off any of you? Are you good enough that it doesn't even matter? Or are you going to be picking up Rock Band 2 and don't really care for this Guitar Hero: World Tour business?
