That time of the year has begun over at GOG, as their Sleepy Sheep Insomnia sale is currently underway.

For those who don’t know how the sale works, GOG will put up a game on a special discount with a limited number of copies. Once the copies for said game run out, they will rotate to the next game on the list and this will continue until the sale ends once all the copies run out.

They’ve also created an incentive for those who are committed to staying up all day, as if you buy 10 titles through the Insomnia sale, you will receive a code for a free game.

You can head on over to their website and keep your eyes peeled for any games you’ve been waiting to buy on sale.

Author’s Note: The sale you see above has since passed.
