Okay, so my sister and her boyfriend have birthdays only 2 days apart, so they just have a birthday weekend, and I want to get her bf a present too. I know what to get my sister (Going to get a framed picture of her dog), but for the boyfriend, I don't know him that well.

I noticed he does have a PS3, with half a dozen games. I think they play a lot together, my sister used to be huge on Mario Party 2 and Mario Kart 64. He is a huge car buff, and he already owns GT5, so that's out, so what should I get? I think you'll understand his taste after I name a few of the games he owns

FIFA Soccer 2013
LittleBigPlanet 2
Gran Turismo 5
NBA 2K Something..
The Sly Collection
maybe MLB: The Show, but I can't remember
Something else like Sly/LBP, but I can't remember

and a few others. Any ideas?

I'm thinking about the ICO/Shadow of the Colossus Collection, but I dunno. I might get him Portal 2 because it's so damn funny, and non violant (which I think is important to him, I don't think he would like anything with guns).

P.S. They aren't married, so technically he isn't my brother in law, but they live together and been dating longer then most people can maintain a marriage, lol. I think they are waiting on my sis to finish her PhD.

Why not sly4, if he likes sly collection. Also if he likes racing game , the latest need for speed game is not a bad idea

Flower.

give him a wii, a remote and nunchuck and let him playone of the best games last gen - Super Mario Galaxy.

Uncharted 2 or 3

Need for Speed Most Wanted, Sly Thieves in Time, Jak or Ratchet & Clank Collections, or maybe LittleBigPlanet Karting(don't crucify me for this one)

EDIT. Or maybe a prepaid for 3 months of PS+?

Give him a 360 with forza 4.

Apart from ICO/SotC and Portal 2:

Portal 2 should be a great choice or maybe The Walking Dead game serie(the TT GAME).

Rhythm Thief and the Emperor's Treasure

Mario Kart 7

Sonic & All-Stars Racing Transformed (3DS for 3D)

Lego Batman 2 (the Wii U version is the definitive version)

Lego City Undercover

Lego City Undercover the Chase Begins

Need for Speed Most Wanted U (the Wii U version is easily the best)

I wish I could think of more with that list of his favorites.
