GOG.com has launched the ultimate trans time-zone deal again: the Spring Insomnia Sale is upon us! Gamers from all continents will get a chance to get celebrated titles at up to 90% off discounts–and free games in very limited numbers as well. Starting onMonday 12 May at 2:00 PM GMT and running until GOG.com is out of stock, this promo has plenty deals worth staying up for. The rules: games will be on sale only one at a time in limited numbers of copies. When the stock of one game–marked on the promo page with a counter–runs out, another game is up.
