I know I'm super late to the party, but Valve's Steam service for offering video games is awesome.
I joined last week to get ready for a LAN party my friends were having, and was pleasantly surprised that I stumbled onto a sale. Before I could say "Minimum Requirements", I had 6 games in my cart!
The main game I wanted to play (Day Z) required the purchase of some beefier equipment than I had, so I'm typing to you now from my new laptop, which I think I will actually keep this time.
The experience with Day Z was awesome, and I think I've picked up my previous addiction of gaming. I downloaded a game I love (Star Wars: Knights of the Old Republic - some creative tweaking needed to get it to run on Windows 7), some franchises I've missed out on (Batman Arkham and Assassin's Creed) and psyched to try out Rockstar's L.A. Noire.
I now intend to make the most of the kids napping and play video games for several minutes.
Take care all!
