My crotchety old father wants a PS3???

 My old man has never looked highly upon video games. Even when I was a kid and he bought us a Sega Master System, he did so grudgingly. 

And today, at seventy-two years of age, he still claims to feel the same way. "I don't know why you waste your time with that stuff," he said to me recently. "Video games are for kids. It's embarrassing."

But over the holidays, he started asking question about Blu Ray players. I told him what I know, completely avoiding the PS3 because I figured he's just dismiss it as a gaming device. THEN he tells me that...get this...HE WENT TO A GAMESTOP and was asking questions about the PS3! He went on to say that he seriously considered buying a PS3. But when he looked at "the wall of games" all he saw were "games where you shoot other people." This really put him off. 

I feel like we made significant progress, but I don't want to let him cool on the idea of a PS3. So I ask you...

Can anyone recommend some high-quality PS3 games that really showcase the system but don't have anything to do with shooting people? In fact, the less violent the better. I only own an XBox 360 and a Wii, so my PS3 knowledge is sorely lacking.

Any help you guys can offer would be appreciated. Thanks!
