However, all I can say is this: This is the most frustrating game experience I've ever had. We started by having to download an Xbox console update and then continued by having to download a ROCK BAND update. Then, we began playing, only to deal with the Onkyo received shutting down after a few minutes' play (not sure why, but presumably a power or thermal issue). Then, the Xbox stuttered regularly trying to draw the screen (thermal issue? something else?). The guitar crapped out after a few minutes - it usually won't strum down, and sometimes stops strumming altogether. Oh, and the included drum kit barely works at all - I'm good at these kinds of games and I could barely get above 30% notes hit on Easy, which suggests that I'm doing something incredibly wrong or the drums just don't work properly (jhitchin - what was your experience?)
I've already put down $125 deposit to EA tech support on a replacement guitar... let's hope that one works OK. In the meantime, it would seem that the neither the hardware nor the software is of release quality yet.
