My story isn't all that different from many other males my age. The majority of my youth was spent with a NES or Genesis controller in my hands. As I aged I spent less and less time playing games, and even skipped a few console generations completely due to things like girls, work, and higher education. Earned the degree, got the girl, found a good job, and even threw in a few kids in the process and now I'm back to gaming.
I actually started back a few years ago with the original XBOX. I played the hell out of a few sports games and Ninja Gaiden, but never really found my groove. I tried titles like Fable (ok), Halo (fine), and Morrowind (I was doing something wrong because I just didn't get it, wtf was up with the combat?), and none of them ever grabbed me like I hoped. This generation I opted for the Wii. A return to Nintendo roots and I convinced the wife the kids could play it in a few years. I know Wii is a dirty word around here, but say what you will, it drew this dude back in a big way. After about 5 minutes with Super Mario Galaxy I was reborn. Sadly the selection of games has cooled considerably (until summer 2010), but I've still gotten plenty of use out of it by grabbing titles I missed during my hiatus. I am also looking to add a PS3 to the fold in the future, hopefully sooner rather than later.
