The digital distribution platform GOG has just launched their massive Spring Insomnia Sale. The event offers 100 different titles with up to 90% off, ranging from small indie games and old school classics to huge AAA releases. You have to be quick though, as there are a limited number of copies of each game available. Once all those copies are taken, the deal is removed and a new one takes its place. It is called the Insomnia Sale because many people go without sleep for the entire event to try and get all the best deals.Click the link above to join in with the GOG frenzy and pick up some very cheap games before time runs out.
