Square Enix has just put all of their Fire TV Games on sale at half price. Final Fantasy III, Final Fantasy IV, Final Fantasy V, and Final Fantasy VI are all $7.99 right now. These games are normally $15.99. Also on sale are Adventures of Mana for $6.99 and Chrono Trigger for $4.99. These games are all compatible with every Fire TV model except the 1st generation Fire TV Stick. Most of the games are playable with the Fire TV remote control, but some do require a game controller. Check the “works with” line on the product listing to know which is which.
I don’t think FF IX is 50% off, it is lower – but definitely not 50%
