Guitar Hero III: "We Tried Too Hard"
One thing I liked about the previous games were their large variety of song lists. Unfortunately for me, who preferred songs like "Soy Bomb" and "Jessica" in Guitar Hero II, seemed to feel empty with the heavy metal/hard-rock approach of this third installment. The developers seemed to mainly cater said genres of music, although there's nothing wrong with "Paint It Black" or Reptilia, in my opinion.
Another aspect of the game that I really thought we could have done without was the battle mode, and the focus of it during campaign and multiplayer. When I want to play Guitar Hero, I'm hoping to just have some friends jam together in a little co-op or the occasional face off. Instead I'm now subject to, for some reason, people's urge to play battle mode.
Maybe it's just me, but Guitar Hero used to be more fun. The core gameplay still follows the same formula, so I still appreciate it for what it is, but who said that it needed to be changed. Neversoft added their own spin of Harmonix's baby, but for some reason it seems they tried too hard to outdo the previous developer.
