Have you collected absolutely everything there is to collect for your museum in Animal Crossing: Wild World? Racked up three stars in every cup in Mario Kart DS? Completed all 40 of the challenges in Contra 4's granite-hard Challenge mode? Cast your modesty aside, dear reader, revel in your own gaming greatness, and share the DS-related achievements you're proudest of.
(Note: We're only joking about the Contra one, incidentally -- that's just fricken' humanly impossible. OR IS IT?)
