Unbelievable !! ... bad

a) no party mode,
b) no duet opportunities for all the songs,
c) no gameplay like Give the micro further, Achieve first X points etc.,
d) no different difficulty levels,
e) not have their own player profiles,
f) no choice of song lengths (short / long)
g) no online Battle,
h) any add-on for Dance + Guitar mode,
