The Guitar Hero games are not bad. However, they need better choices of songs in some cases. I think Television's "Marquee Moon," King Crimson's "Lark's Tongues in Aspic, Pt. II," and Frank Zappa's "The Torture Never Stops" need to all make appearances. For Rock Band, I'd kill for The Cure's "Fascination Street," Metallica's "Sad but True," and/or Rammstein's "Morgenstern." Otherwise, they're not bad... would rather it was one game and new songs were added by DLC, though.
Yeah, I love Guitar Hero. It's my second favorite game next to SSBB. Thing is, I only have Guitar Hero On Tour for the DS and GHIII for the Wii. I can pretty much pass every song on those two games except for dreaded Raining Blood and TTFAF, of course.
I for one don't like playing the game, though I watch people play it. I don't know why, but I just do. I've watched a lot of WT videos, and to be honest, the charts look pretty easy. I just hope there's really good songs for download
