If I have any regrets for 2007, it's that I didn't play enough video games. And Slate's sprawling epic gaming conversation (17 printed pages) is full of proof that I missed the year's most important cultural happenings. Sure, I put in my time with Desktop Tower Defense, threw the Wii control around a bit, and dabbled in Halo 3. But I didn't play Rock Band, I didn't play BioShock, I didn't play Portal, I didn't play Super Mario Galaxy... I didn't even play Scrabulous!
