Loving the game so far. I play drums 99.9% of the time, so RB3 is just awesome for me. Some great new songs to play, and I basically get to relearn everything else because every song has pro drum mode now. FYI any Boston in Pro/Expert mode: So damn good. Tonight will be the Rush marathon (in between Rangers innings at least).
I'm stoked that Rilo Kiley and The Smiths made the cut. Not just DLC, but in the actual game. Nice! I hope that means more from them will come eventually. Give me more from The Sounds while you're at it, HMX.
And I know this is lame, but I can't play for five seconds without my kids running into the room, so I'm glad the new game is a little easier make family friendly. I set up my band with four normal looking humans, all wearing actual clothes. And I get them whether I quickplay or do the career stuff. Cool!
The interface in general is much improved over RB2. Everything is within a couple button presses of everything else. No more 10 circle clicks to back out of career mode.
Last snag left: Waiting to import my RB2 songs. Not that big a deal, as everything I play is DLC anyway.
SlackerCS on PSN if anyone wants to compare pro/expert drum scores.
