What should be the next PS3 game ?? (Just bought a 60GB)

I just bought a 60GB and my first two games were

-Metal Gear Solid 4:Guns Of The Patriots Limited Edition

-Ninja Gaiden Sigma

I love both of them and of course I've beaten and enjoyed MGS4 (didn't go far on NGS since Im still having fun on MGS4 a bit)

But, since im a little bit not on time for the gen (a little late) I was wondering..what should be the next game I should get ?

We have GTAIV,Oblivion,LBP,Mirror's Edge,Fallout3 And many more.. I love RPGs of course and action/adventure games and shooters but,

what do yo guys think should be the next game for me ???

Well if you like rock or music, Rock Band 2 is definitely 4 u.hghf

Out of those titles you listed, I enjoyed Mirrors Edge the most. raven_squad

Burnout Paradise, CoD4, Uncharted, Resistance 2. LittleBigPlanet.

You can't go wrong with any of those, but I would save my money for Killzone 2.

i think you should go for old titles first like Uncharted, Valkyria Chronicles, R:FoM & R2, Heavenly Sword, etc... then save some for Killzone 2 as well.
