LOL @ your friend who said The Club... wth is he thinking...

I'd say Ratchet and Clank.

Call of Duty 4.

Hands down.

Everyone that says Ratchet and Clank, only does so, so that a PS3 exclusive wins.

Seriously, if you've played any of the first 3 or 4 RoC on the PS2 (which most PS3 owners would have I would assume) then you're pretty much getting the same thing here. The only real pull being Insomniac's imagination with weaponary (which is why I'm more hyped for R2 than KZ2).

CoD4 pushed alot of barriers (particularly in political correctness), and a company that changes up the formula when things get too stale? not many can say they do that (The only one I can think of that screams SONY is naughty dog).

Ahem.

COD4 added a modern setting and some new places. Oh, and some perks.

Tools of Destruction added at least 3 minigames, Robo-Wings, new weapons, updated graphics, an entirely new story and ended up being one of the best games on the PS3. I would say it's third, in fact.

1) MGS4

2) Oblivion

3) Tools of Destruction

4) Uncharted

5) COD4

EDIT: And if you have played any of the R&C games on PS2, not owning a PS3 is stupidity and owning a PS3 without owning TOD is HERESY!

And yet some people do, because (not at all biased) Gamespot gave it a 7.5. Then proceeded to give Braid a 9.5.

Call of duty 4 without a doubt. And certainly not Ass creed

R&C:TOD/GTA IV = SP
COD 4 = MP
