GOG.com announces the return of their "infamous" Insomnia Sale, which offers limited quantities of games and rewards sleep depravation (thanks Acleacius). Here's a bit on how this works:

You lucky Insomniacs will also be treated to a number of games never before seen on GOG.com as well as the best-ever deal on our crowning jewel - The Witcher 3: Wild Hunt (-50% after the recent price drop, that's $24.99 in the USA).

And, because we're not entirely sadistic, we're even offering bonus freebies to the sleep-deprived. Buy 10 games, get a random extra one for FREE — keep buying and they'll keep coming faster and faster!
