the duel mode -lrb- one on one -rrb- be very , very unresponsive . rancor be sluggish . pick up item take too long to highlight and throw -lrb- destiny and rancor -rrb- jump do not always work , you need to jump again or again again . pod racing be somewhat reasonably responsive . all in all I give it a 4 . at least once they admit there be a problem , they will send a fix to XBOX Live .
