I absolutely suck at it, but I started a save on SimCity 3000. I have a lot of learning to do because my city is 100% dying, so I should probably run through the tutorial...
I have also been doing very minor chip damage on completing Gemcraft: Chasing Shadows. I'm far enough along it takes a long time for me to beat any levels. And probably even longer when I finally am able to beat the 200+ wave level.
I also discovered that Portal is now 7.63GB in size currently, after buying The Orange Box for $3.99 and wanting to check out a mod I found for Portal that I didn't realize wasn't released yet. Don't know how big the game originally was on launch, but now it's nearing the 11.88 GB size of Portal 2, which I find insane.
I also kept failing at Zuma Deluxe due to bad luck and skill issues on my end.
