I've kind of lost my taste for the first person shooter games. I've been playing them since Wolfenstien which i got on 5 1/4 floppies. So to me, the graphics keep getting better, but it's all pretty much the same thing.
CSI was fun, my wife and I enjoyed playing that together. Which reminds me, if you're a fan of brain teasers and puzzle games, look at the Myst series. Very fun, very challenging games. My wife and I loved playing those together.
