Guitar Hero 3 or Rock Band?

which one will you choose? I was set on rock and until i saw the stage demo from E3 for guitar hero 3 and now i am all hung up on guita hero. what do you guys think?

I had Guitar Hero the first, but I'm passing on these other new games because they're just rediculously expensive. If I want a music or rhythm game, I'll pick it up for the DS from now on. (I paid 60 bucks for Guitar Hero, and that was worth it... but 90+? cha' right.)

I probably won't get either of them this year, but I'll probably get GH3 early next year.

I'm gonna get Rock Band, so I can take my 360 over to my mom's house and my wife, mom, little sister, and myself can all play it together.Shattersword81

Yeah, I'm going with Rock Band all the way because the guitar looks sick, the drums look like a blast to play, and there are actually vocals!!! This game is going to rock hardcore, plus, you can play online with your buddies if they have it! I can't wait! I actually might pick up the game GH 3 though but not get the guitar with it depending on how much cheaper it is.

Rock Band looks really cool, but people singing on xbox live? ugh i just hope people dont f**k it up by not singing and being g*y on it
