GOG's annual Insomnia Sale has started.
GOG's annual no-rest-for-the-wicked sale, Insomnia, has returned once again. The sale only discounts one game at a time, until quantities last or for a set amount time.
You never know what's coming next, or how big of a discount it's going to be, so you have to keep refreshing, hence the name. The site did not mention any specific games you should look forward to, but promised to feature games completely new to the service.
In addition, you get one free game each time you buy ten games, for as many times as you want.
The sale will conclude when all quantities run out, so there's no solid end date. As with all GOG products, they're all DRM-free.
