Wow. In the absence of a real story-mode, I totally expected it to have something like 8 tracks from each game (not to mention re-arrangements/remixes). All included. Core gameplay is great, but this is not nearly enough content for $40. I can't help but feel like I got ripped off here.
Stay classy SE and DLC as a whole!
In reality the 70-80 tracks on the cart is quite substantive for a rhythm game. Unfortunately it does give the impression of being barebones because of how it has to dedicate a mere handful to each of thirteen games. Feels like it hasn't done justice to most of them.
