I don't care about PSN level, or about how many games I have etc, but I got a few I'd rather not have on my list...
Sackboy's Prehistoric Moves - What a piece of shit that was
Mushroom Wars - Only have it because I had a Kmeaw cfw for like a week, and that was a game I got for free
Pain - Same as above
Trash Panic! - Bought it when I was pissed, can't get a single trophy on it 'cause a) it's impossibly difficult and b) it's shit
Madden NFL 11/12 - Played with a mate at uni, don't own either, so never going to platinum or get anymore trophies...
Rugby World Cup 2011 - Same. And it's terrible.
DC UNIVERSE ONLINE - It was free to play, but apparently you have to pay to get the trophies. And it's terrible.
That's about it...
