It's a pretty damn good game so far and a fitting successor. I'm trying to get out of HD Remix timing, so there's a little hump there. Online matches are a little laggy and there's an optional install with a looping song that's going to drive you crazy... and then you'll look for the song to add to your jogging playlist.
However, if you want to play single player, turn off the arcade join-in setting. I was getting HERE COMES A NEW CHALLENGER every second.
Still playing, so maybe more impressions later. You'll probably have it by then though.
