i will try it first ... but for ninja gaiden ... i already played the first on xbox.

If you only got it for one game you will realize that there was a lot more you were missing out on:

Uncharted
Heavenly Sword
Folklore
Warhawk
PixelJunk Monsters / Pain
and possibly the Ninja Gaiden remake cause that was actually pretty fun too.

I loved all of these titles although I'd skip the PSN ones to play the first four anyday. BTW getting a console for one game can only be justified if that game is MGS4.

Forza cannot even compare to Gran Turismo.

no man i played both of them and found forza better than GT ... the control is better and game play is more fun ... ( in GT cars slide alot like the street have soap on it ) ... also FORZA have car crash.

The "Full" setting in the RGB options will make some TV's appear way to dark, set it to full, then adjust the TV displays, it works out amazingly :) If your TV is already tweaked to your liking, you can set it to "limited" to brighten it up a bit. It's all preference though :P But between you and me, I believe my PS3 knows more than my TV does, so I adjusted the Tv ^^
Games that you MUST own.

Ratchet and Clank Futures.
Uncharted
Metal Gear Solid 4
Warhawk!!!!!!!
Super Stardust HD (PSN)
Pixeljunk Eden (PSN)
Motorstorm
Resistance Fall of Man
Burnout Paradise (if you don't have it :P I haven't been reading all the posts I'm afraid)
Pixeljunk Monsters (PSN) although the game's awfully hard ;-;

Folklore and Heavenly Sword are GREAT games, but they don't appeal to some :P So that choice is yours, but just between you and me, I'm on my 7'th run-through of Heavenly Sword :3 I LOVE that game. @NJ5, yeah you can totally button mash against the easy guys :) But then again... you can do that in almost any action game ever created :x So I'm not sure that's totally valid.

thnx for the advice man & iam interested in Folkore more than heavenly sword because some guys said its gameplay a bit like rpgs.

If PSN games are in consideration I would suggest Super StarDust HD.
Also you might wanna try the Pixel Junk Eden Demo to see if you like that.

Why choose a side?  You bought a PS3, which means that you have graduated from Fanboy to Gamer.  You can still have a favorite, like I definitely favor the PS3 over the 360, but I can see the good in both sides and no longer feel the need to bash the 360. 

Congratz to u and ur ps3, u should wait a little for the platinum games like Resistance 1, Motorstorm, Uncharted, Ratchet and Heavenly sword.

Congrats on your new PS3, NNN!
