The biggest surprise about Lego Rock Band was the Rock Power Challenges. I play the drums, and it felt so much more authentic and fun without overdrive enabled. After realizing this pleasant surprise, I went to check the game modifiers/cheats to see if I could somehow play any song in this mode. Unfortunately it isn't an option.
I would love to see it as a game modifier or as a separate game mode in future rock band releases. I've just about gotten sick of doing crappy drum fills 20 times throughout a song, and I prefer not to worry about overdrive.
Does anyone agree with me, or am I just crazy?
