I highly suggest you aim for your assassins creeds games. Then after get Batman AA, Black ops, and then lollipop chainsaw. Of course DEADPOOL must be platted before all of this lol.
Unfortunately my internet isn't good enough to play online matches for the Assassins Creed games But a good call of the Deadpool plat as I just unlocked it for my 15th. For your next one lets finish up Prototype, only 1 more trophy to go!
Holy crap! Too many to name. Finish something. Anything.
Hitman seems to be a good choice. I can tell you that you don't truly know how detailed and intricate the game is until you start mopping up the last of the trophies. You end up coming across some really cool stuff.
