Our friends over at GOG.com have kicked off a stellar summer-themed promotion that'll land you Runic Games' Torchlight for free (yes, for free), the ten-game Definitive Dungeons & Dragons pack for $21.10, and many other titles at a ridiculously low price. Word is that they will "have three weeks of 500+ games on sale for 50% or more and daily deals up to 85% off", so you'll want to keep an eye the digital download vendor well into July.
