Then its crap then. Sorry, but it is.
Its based on DDR, which is based on accuracy, and if the whole basis is still on score, which accounts for having Perfects/Marvolouses/and greats, and getting a full combo, then its poor that the engine doesn't allow you to do that. Its useless... its always annoyed me that the beats went off, etc while playing the online version. Pointless, pointless, pointless.
