Valve has launched a massive sale, officially being called the Steam Exploration Sale, on some of the most popular games of the year - and thousands others - just in time for Black Friday. For the next six days, gamers can take advantage of sales throughout the Steam store in addition to a new batch of daily deals each day.

Today's daily deals include Sid Meier's Civilization: Beyond Earth at a 30 percent discount, 40 percent off Lords of the Fallen and a 50 percent discount on Watchdogs, Counter-Strike: Global Offensive, Goat Simulator and The Long Dark.

It only gets better from there as The Evil Within can be had for 66 percent off while Company of Heroes 2 and Don't Starve (solid advice) are being offered at a 75 percent discount, bringing their totals down to just $9.99 and $3.74, respectively.

The Steam Exploration Sale conveniently ties in with the Steam Discovery update released a few months ago. In your Steam account, you'll find a section called "Your Exploration Sale" that'll recommend games on sale based on titles you play and what's in your library.

It's common practice for Valve to launch a Thanksgiving sales event. Despite the fact that it's typically a smaller affair wedged between its summer and Christmas sales, there are still plenty of solid deals to be had as seen above.
