I played RB3 all afternoon. Got the three free Doors tracks, had fun playing those. I like the new menu system, the way players can drop in and out quickly and easily. I like the new challenges (go into overdrive as many times as possible, get as many streaks as possible, etc) and there's a lot of great tracks. Failing out of 'Freebird' got me all nostalgic for 2007.
I'm still sad about losing some of the tracks that won't make the song export from RB2, because a couple of them were favorites, but I'll deal. Overall, I'm really pleased with this game. I can't wait to dig further into it and eventually check out the pro-mode.
