[quote name='Rig']If you have other (better) DDR mats, I would say wait until an adaptor is released so you can use those, and pick up the game without the bundle. That'd save some money right there.
This one has its share of issues. Quest Mode is horrible, the "Perfect" and other words are too close to the arrows, the arrows themselves are smaller than usual, and the default "Vivid" color of the arrows blends in to the background too often. It's harder to tell the 16th notes and such from regular notes.[/quote] One thing to note about the mat is that it, like any other 360 controller, can be used on a Windows computer, and should be pretty easy to make use of through the XNA framework.
I didn't like quest mode much, but that is because I jumped into it a little too soon (this is my first DDR and I suck). Regardless, there are some pretty evident problems with the mode. I haven't really noticed any problems with the text position or the arrow colors, but I am playing on the lowest difficulty (where it wouldn't be as noticeable) and I don't have anything with which to compare it.
