If your Final Fantasy collection isn't as complete as you want it to be, then now is a good time to stock up. To celebrate Golden Week—a period packed with lots of Japanese holidays—Square Enix is selling most of the series at a 50% discount.

In North America, the sale includes Final Fantasy 3, Final Fantasy 4: The After Years, and then all games 5 through 10 (plus X-2). You can also pick up all three parts of the Final Fantasy 13 trilogy at the same discount, and the Pokémon-like spin-off World of Final Fantasy at 30% off. In the EU store, the sale also includes Final Fantasy 4 but, bizarrely, Final Fantasy 9 is only 40% off, rather than 50%.
