What should I ask for Christmas? (20yr old nerdy guy)?

Hey everyone, I'm a bit stumped on what I want for Christmas. I'm heading home for the holidays, and although I don't want any presents my parents have decided they're getting me at least one, and I can decide what I want or have them waste some money and probably get something I don't like too much.

Now, I used to be really into games. PS3 and a pretty lame laptop are what I've got (by lame I mean runs games on low settings, used mostly for school work.) I don't really play games too much anymore, I'm normally too busy hanging out with friends or doing schoolwork, but I was leaning toward getting a PS3 game or something. I'm really open to anything except clothes. Giving something functional like clothes as a present kills the point of a present to me.

Little background on me; I live without a TV most of the time, but could still play games when I visit my family. I have the aforementioned laptop on which I've played WoW and LoL casually, but don't really like spending money on them. I'm leaning toward getting a PS3 game, but have no idea what I want. I like RPGs, MMOs, and shooter games. Other than that, my hobbies mostly include things that I don't have to spend money on, so it's a no go there.

Anyone have some good ideas? Some awesome games that would be enjoyable, or perhaps other gift ideas? I'm open to anything, just curious to see if I stumble upon a good idea here. Thanks in advanced for any answers :)
