Query: Difficult

I played the arcade version of this game. The song selection is much bigger then Konamix's, but it is still a lot like Konamix. It shares certain songs and of course, introduces some new ones. I found the thing with holding the arrows extremely difficult, I am a seasoned DDR player and I failed some normally easy songs because of the stupid hold steps. A lot of people might like this game but it frustrated me to no end. A good point is that they did not change this one from the Japanese version. Even though it is a hard game, I still say Rock On DDR!!!
