depends which you game you prefer,
replay value, the 2nd one wins if you like cutey stuff platforming + racing
quality, i prefer the first one, even though the first 2 games are playable in the ps2.
if you want multiplayer, the 3rd one. story is good for Uncharted 2 and decent multiplayer. not sure with MoH, i just played it for 1 hour.

maybe the 3rd, since you can buy the other games cheap anyway. LBP GotY edition is below 30$ now, as well as GoW 1&2, Modnation Racers and GoW3, about 30-40$. MoH, about 40$, Uncharted, 30$, since the GotY edition is out already
GotY edition = game + all DLC

the third one

Well...it's your money, not my place to say >"<

Also hi Kaiser

id say get the get the 1st or 2nd one and pick up black ops

because you know you want black ops more than MoH

hmm If it were me, I'd get the LittleBig planet one. but like Lunar said its your money so yeah
