The GOG.com DRM-Free Summer Sale is on and popping. It's 18 days' worth of savings, ending June 30. A constant stream of 200 flash deals (a handful of games at a time, lasting one or two hours) will be up to 90 percent off. Plus, two new bundles each day whose savings stack up to 85 percent off will hang out at the top of the page. And 700 more games, up to 50 percent off, run the entire length of the sale.
In recent years, the Steam summer sale starts about mid July, so, if you're feeling gun shy, you've still got a month to go before emptying your Steam wallet.
