Magic the Gathering - I like this so far. For the price of a starter deck or so I can just futz around with Magic: The Money Sucker and have fun. Granted, my real cards go a little unloved as a result, but I rarely play anyhow. Bonus? Online play. Haven't tried that yet; still getting whipped around by the computer.

Puzzle Fighter HD - fun enough. More of a "play with friends" title for me.

Worms - same as Puzzle Fighter. I loved that game on PC, though :)

And needless to say, I'm looking forward to playing Mark of the Wolves when it comes out. Hopefully the don't try altering the graphics... SNK games need their pixilation! Its part of the style!
