A couple technicalities
Played and completed all songs on DJ Hero 2 on bros 360 but technically you can't complete it.
Finished several characters story modes on Playstaion All-star Battle Royal bit feel I'd have to do them all to say I've completed it.
Edit Again: Deleted Child of Light from my ps4 list, never actually completed it. (Rhyming drove me away, I'm afraid I couldn't stay.
