The first thing everyone notices about Rock Band is the fact that it is more or less a copy of the widely revered Guitar Hero. The second thing the notice is that it has two more instruments: drums and vocals. To all the ignoramuses out there who said "What the hell, they're stealing Red Octane's idea!" You all deserve to be fed to Swedish mountain goats because the guys who made Rock Band are THE SAME GUYS who made GH1 and GH2. Let me explain: After Guitar Hero 2 was made, the developers, Red Octane and Harmonix, split up. Red Octane went on to make Guitar Hero 3: Legends of Rock (disappointing), and Harmonix went on to make Rock Band. And their "idea" isn't actually theirs: there have been several games before Guitar Hero which attempted to accomplish what the GH series did. But enough about that. I'm going to point out everything Harmonix did right and wrong in Rock Band.
