Burnout Paradise - Easiest Platinum IMO

Uncharted - Rather easy but be ready to play the game at least twice.

Batman: AA - Also easy, it can be done in one run if you choose the Hard difficulty right away. The Challenges are quiet challenging(...) but it can be done with some practice.

Call of Duty: WaW - I think it stands in the easy ones.

I only have 2
dead space ( I had to finish it like 3 times)
and Little Big Planet (it was really easy)

I just need to finish RE5 on the hardest to get plat

and KZ2 I only need the online wich I think KZ2 plat is really a pain in the ass for plat.

i would recommend you (terminator) you only have to finish the game and finish it again on hard or you could just start from hard finish the game and get the platinum. anther fairly easy and fast platinum is WWe legends of wrestlemania, also need for speed undercover is very easy,uncharted as well(my first platnium) if you want to add me my psn is (eviltaker10) i am also a trophy ho! :)

Terminator salvation. Finish the game in easy mode, then in hard, you should take +- 5 hours. You can go directly to hard but i recommend finishing first in easy.

So I guess terminator is a rent :P

a complete playthrough in just 5 hours sounds kind of lame though. :S

But I actually have the platinum trophy for it so I am posting from experience!

if you can stand that game for 5 hours you already earned the platinum.

Uncharted is an easy pick for me, Batman AA wasn't really hard either except this one particular challenge room which proven to be a pain for me.

Prince Of Persia

That's the only one I have. I'm really close to get a platinum for RE5 too.
Heard that Alone in the dark is really easy to get platinum. Also heard that it' total crap though!

Trivial Pursuit was real easy. Found a platinum roadmap by googling. Took about 4 hours.

w@w and Godfather II
