I haven't been too keen for this one, I might wait until it might drop to $0.99 like so many other Gamelofts
I would recommend this game to anyone that likes guitar hero. It is the best guitar hero experience on the ipod touch/iphone(out of the game i have played.) Im not seeing any lag and i am on 3.0 on my 2g ipod touch. I bought it at $6 and dont regret
You don't have the notes suddenly slow down for a few seconds at times during the songs? Weird, I am on Touch 2g as well, so I don't know what gives there then.
