To be perfectly honest, I was growing totally weary of the Project Diva series. The earlier games up until F were fun even with those troll songs that were nigh-impossible to clear without using assist items, and they helped me a lot with getting over motion sickness. However, F 2nd took the trolling to a new level, requiring all songs to be cleared to plat, including the deadly ones on Extreme. That was the last straw that broke the alpaca's back. Dropped it and never played X.
Even so, I still wanted something to play that had elements that are completely similar or even just reminiscent of that system. Miracle Girls Festival was just what the doctor ordered: 100% Project Diva style, No troll songs, and has almost all of my favorite characters in one moelicious little package.
