GOG.com has begun their Summer Sale, as of June 8th, and it has some fairly deep discounts in it. First, if you sign in to their GOG Galaxy client, they will gift you a free copy of System Shock 2. Second, The Witcher III is 50% off again, or you can get the game and all of its DLC for the price of the base game (which ends up working out to 33% off).
The top seller is the Homeworld Remastered Collection, which has been reduced to $17.49 USD (50%-off). You can also get either The SOLUS Project, which released this week, or The Witness for 15% off. Then we get to some of the game bundles, like all of the Tropicos or a bunch of Bullfrog titles for 80% off. You know how these digital game sales work.
They are also doing an XP system. If you buy games, check in, or do a few other actions, you can accumulate points that will unlock a handful of free games. The three that they're offering me are Spelunky, Gabriel Knight, and Dreamfall Chapters. I'm not sure if it's the same for everyone, though.
