I want to give this game a fair shot, but my excitement has dwindled to be honest.
I was reading Ars Technica's article, and these are the parts than turn me off to the game:
These are my interest-killers for the game. This is counter to main reason why GH ad RB games were so compelling; this would feel less like you're "creating" the music and more like you're simply tapping along to an mp3 track. It feels less "interactive". That's why I hated GH's multi-instrument mode and was happy HMx kept RB "pure" in that sense. Music playing regardless of what you're doing with your controller was totally contrary to the premise of the game. RB3 and Unplugged on PSP still felt like you were "creating" the music, and the use of master tracks conveys that feeling. (and was really cool to hear single elements of songs). However, perhaps that's intentionally not the point of this game (i.e. it's not supposed to be a simulation of playing the music). In which case it doesn't really interest me.But by reducing the complexity of the standard Rock Band rhythm tracks, Blitz feels a bit more disconnected from the music that you're supposed to be playing. In Rock Band, following a complicated progression of notes on the guitar or drums was almost like reading sheet music that outlined what the coming notes would actually sound like....
What's more, the tracks that you're not currently working on play just fine without your direct input.
In Blitz, on the other hand, it feels like you're just twiddling your thumbs to some pretty background music rather than actively playing that music.
I've kinda went from excited to I'll never really play it but will buy it for the RB3 track pack functionality.
