So far my favorite game for the PS3 is Killzone 2, I have not been able to stop playing it. I can not wait to play it online.So what is your favorite PS3 game ?

Uncharted: Drakes Fortune without question. Killzone 2 isn't far behind either. 

well i have to say uncharted but  after playing infamous i might change my mind.

Since I dont have one, the ones i want the most are MGS4, Valkyria Chronicles, and Infamous.

Killzone 2, MGS4, LBP, Infamous, NG sigma. Uncharted, R&C, Resistance, tons of PSN games, and im really looking forward to the PS3'S future. 

MGS4

Uncharted Drakes Fortune or Valkyria Chronicles.

I don't have a favorite, but I am playing Battlefield: Bad Company and I am having a blast...get it...!

inFAMOUS! It's so fun! I've spent more than 30 hours on it and it's still going. 

I would have to say inFamous or LittleBigPlanet. I've become quite an addict of Killzone 2 as well.
Ugh. Who am I kidding. The answer is Burnout Paradise.

Burnout

Fallout 3

inFamous

I think I'd have to go with Ratchet and Clank: ToD as my favorite game so far with Soul Calibur 4 as a close second. 

Uncharted: Drakes Fortune at the moment although Valkyria Chronicles is slowly replacing that.

MGS4, inFamous, Uncharted, Valkyria Chronicles, the MLB the Show series.

Uncharted: Drakes Fortune
Metal Gear Solid 4
Flower

MGS4. Not my favorite in the series but I still love it . I also like LBP and looking forward to pick up inFamous when it gets cheaper.

exclusive? inFAMOUS

I love MGS4, but honestly?  I think my favorite PS3 game may be flower.

Killzone 2 at the moment. I haven't had my PS3 very long though...

Uncharted or inFAMOUS    Haven't beat inFAMOUS yet so opinion on that game isn't firmly set, no free time.

Valkyria Chronicles

Think i have to go with Uncharted: Drakes Fortune is probably the best game i have played in terms of keeping me going back. Think i beat it 4 times. But i also think Killzone 2 was a good game, the single player part maybe lacked some things, but the multiplayer it a really solid experience.

The Eye of Judgement. 

I've enjoyed InFamous the most so far.

A tie between inFAMOUS and Killzone 2.

Infamous or KZ2

Metal Gear Solid 4, or InFAMOUS.

This thread is awesome, thanks for writing up my shopping list ;)

I have to say Infamous or MGS4.

my favorite is mgs4 but the one i play the most is killzone 2.

Disgaea 3.

I really love infamous.

inFAMOUS, though that's the only game I have played on my ps3 so far.

Infamous

Haven't played Uncharted yet though.

I just got mine, but Uncharted is blowing me away.  The graphics, the gunplay, the exploration, it all just fits together.  I've only played the demo and the little part of the game leading up to the demo in MGS4, but that game ain't too shabby either.

Uncharted:DF/Killzone 2. but Infamous should be coming from amazon.com sometime next week, and it seems like I only hear good things about that game.

Uncharted, inFamous, MGS4 and Dead Space would be the obvious choices to pick from for me.

mgs4

Uncharted is my favorite for sure. Every time I go to my cousins place I always play that game.

METAL GEAR SOLID 4: GUNS OF THE PATRIOTS. BEST PS3 GAME BY FAR NO DISCUSSION
