I've mostly switched to rock band, but I'll still buy future Guitar Hero games. I just tend to obsess on one game at a time lol. I played GH3 to death from the day it came out until I got Rock Band for Christmas and I've been playing Rock Band ever since, except for about 10 minutes while I tried the "Dream On" free DLC for Guitar Hero III. It was ridiculously easy so I went right back to Rock Band
