GOG.COM : Possibly the greatest site for gamers ever.
If you love old games then you'd love gog.com (Formerly Good Old Games). It isn't just a website where you can buy your favorite old games for great prices, it's a place where you can regain memories of when you were younger and played these same games. The cool thing I forgot to mention was that all of these games were recoded by people at gog.com. Any problems? You can contact GOG's help page that will give you all the help you need to get your games up and running. Check it out!
