As the title states, this is the thread where you brag about games that you have either the Platinum Trophy/all the Achievements, or achievements and trophies you are particularly proud of having achieved.
As for me...
Assassin's Creed II - 50 out of 50 for 1000
Borderlands 2 - 56 out of 56 for 1250 Gamerscore
Mortal Kombat Arcade Kollection - 12 out of 12 for 200
Sonic's Ultimate Genesis Collection - 34 out of 34 for 1000
Trivial Pursuit - 34 out of 34 for 1000
Let's hear yours!
