GOG.com is the place to go if you remember playing a game as a kid and would love another playthrough on your modern PC. Chances are, GOG has it available to buy, and not at an extortionate price, either.Today GOG gets even better because the DRM-free games service has kicked off its 2013 #noDRM Summer Sale. The best deal in that sale? Action RPG Torchlight is completely free for the next 48 hours. On top of that, over 500 games are being offered at a discounted price with many of them 50 percent off.Filtering through more than 500 games deciding which ones you want to buy isn’t a quick task, and that’s probably why the #noDRM Summer Sale is set to run until July 5th. You can take your time and cherry pick all the games you want without fear of missing out.It’s hard to actually pick out the highlights in this sale as there quite literally is something for everyone. GOG has split the selection down into bestsellers, action/shooter, adventure, indie, RPG, and strategy/sim categories to try and help, though. Mac gamers haven’t been left out and can pick up such classics as Theme Hospital, Stonekeep, and The Witcher 2 all at 50 percent off. And then there’s the bundle deals with up to 90 percent off.As a regular customer at GOG there is one feature of their system I rely on when such a sale is running — if you login to your account before looking at the long list of games on sale it highlights which titles you already own ensuring there’s no double purchases. A simple, yet very useful feature.
