Some of the titles in Good Old Games' catalog are well-known and renowned as being excellent games. The Witcher, Neverwinter Nights, Dungeon Keeper, Duke Nukem 3D, Fallout -- the list goes on, and the fact you can pick up these excellent titles for low prices is great in and of itself. But GOG is also home to a number of less well-known titles, and it's these underdogs that the site is hoping to highlight over the next 18 days.

Beginning today with cult adventure game Sanitarium, GOG will be highlighting a different "hidden gem" every day until July 25. The "hidden gem" of the day will get a 60% discount off its usual price as well as a featured spot on the website. In this way, the sale offers not only the opportunity to pick up some great games for some decent discounts, but also the chance to discover some titles you may not have heard of.

The sale item changes each day at 6am EDT, so be sure to check out what's on offer.
