One of the best things about the PS3 is the addition of Trophies/Achievements. Collect enough and your level goes up.
They got Bronze, Silver, Gold and Platinum (you get Platinum when you get 100% on a game).
The closest games I have to getting a Platinum are as follows:
Assassin's Creed 2 - 92% (Missing 5 Bronze)
Skate 2 - 80% (Missing 3 Bronze, 2 Silver and 1 Gold)
Scott Pilgrim vs. the World The Game - 73% (Missing 2 Bronze and 1 Gold)
WWE Smackdown vs Raw 2010 - 69% (Missing 4 Silver and 2 Gold)
Dead Space - 58% (Missing 8 Bronze, 3 Gold and 2 Hidden Trophies)
So yeah, discuss Trophies!
