I really enjoyed finding an empty server and hopping on while skyping with 3-4 friends.. made it feel like we were all crowded around a single screen with an N64 again
Free Goldeneye mod for source, new version released a few days ago. I had a blast hopping on with some friends, really took me back

My favorite fantasy books I would recommend:
Malazan Book of the Fallen (10 book series) - Steven Erickson
Name of the Wind - Patrick Rothfus (i'm sure you've heard of and or already read this)
Sci Fi:
Enders Game (so much better than the movie) the sequel "Speaker for the Dead" is also pretty good
