This, and I would remove LBP from the list 

.  I might be the only person the world that did not like LBP.
You should also try Flower.  It's the one game on the PS3 that my wife will play.
		
 
You're definitely not the only one to hate LBP. The only redeeming part of LBP was all the user-made content that you could easily access. But beyond that, it was a terribly boring game with clunky platforming. 
Didn't like flower. I beat it though, but I was so happy to finally finish it. A bit to artsy fartsy for me.
	
		
	
	
		
		
			No Metal Gear Solid 4? 
It's dirt cheap now and definitely worth playing if only to see if you fall into the love or hate side. Doesn't matter if you haven't played all the previous games because the story is incredibly convoluted anyway.
Maybe 3D Dot Game Heroes (I haven't played it yet)?
And what about PSN games? I really enjoyed Pixel Junk Shooter, I'm sure others will have plenty of recommendations for other PSN exclusives.
		
		
	 
MGS4 will be REALLY hard to get into if you haven't at least played MGS1 and MGS2 before. And even then, MGS4 is pure fan service, and I don't expect many who weren't fans of the MGS series in the first place would enjoy it much.
I'll second 3D Dot Game Heroes and Pixel Junk Shooter.  3DGH is an excellent zelda clone that has its own unique charms. Buy it if you loved 2d zelda games. Pixel junk shooter is hard to explain, but just watch a video of it and you'll understand.
	
		
	
	
		
		
			Did BO have a lot of cussing? Shows you how f**king jaded I am...
		
		
	 
Ehehe. No kidding. Hell, it wasn't until a few years ago that they started using the f-word in games. Now you hear it just about every M-rated game. The first time I recalled hearing the F-word in  a game was The Getaway for the PS2 (didn't care much for the game though). I was kinda shocked at the time to hear it in a game.
But yea, I don't even notice anymore.
