While you're contemplating when you'll possibly have enough time to make a dent in any of the numerous games you picked up during Steam's frequent sales, let us be the ones to alert you to yet another sale, though this time it's taking place over at GOG. You can save up to 90 percent on 100 titles as part of GOG's "Spring Insomnia Sale" taking place now, or kill some time watching as available copies are snatched up in real time.
This is a different setup than most sales you're probably used to. With limited quantities of each title marked for sale, GOG takes a somewhat Woot Off-like approach. As one title sells out, another is put up for grabs. GOG tells you how many copies are left and as people snatch them up, the number goes down, along with a progress bar.
As expected, the more popular titles sell out faster than others, though it seems like every title listed goes down at a consistent (and rather rapid) pace.
