Not sure why this game requires DDR 2nd remix in order to be played since this basically functions as its own game, but whatever. The songlist has a few harder songs than what you could find in DDR 2nd remix, but theres also a lot of slower easier songs to balance it out with. If you like DDR, then like sure theres probably a song or two you'd enjoy here
I was honestly surprised with Append Club Version Vol. 1, as I would rather play most of the music on here than on the original 2ndRemix. It has the Beatmania classics that I enjoy like "e-motion", "5.1.1," "Diving Money," and the JJ Company songs. The step charts are considerably more of a challenge and balanced out with slower music. Different colored arrows instead of the flat arrows is a welcome change, too. I just find the presentation and style to be cooler and aesthetically pleasing. For a spin-off game, I would honestly recommend going out of your way to play this one.
