Game developer Square Enix has just released five new games for the Amazon Fire TV and Fire TV Stick. The games include Final Fantasy XIII, as well as its two sequals, Final Fantasy XIII-2 and Final Fantasy XIII: Lightning Returns. Also released are The Last Remnant and Murdered: Soul Suspect. Unfortunately, geographic restrictions currently limit these games to customers in Japan, but they’ll likely make their way to other regions eventually.

What’s possibly more interesting than the games is the unique trial period and sale being applied to these games. Square Enix is no stranger to unique sales and they’re continuing the trend with these new releases. All five games are available for free, but are limited to a 30 minute free trial period each. After 30 minutes of play, each game must be unlocked through an in-app purchase, which ranges between ¥2,000 (about $18.70) and ¥3,400 (about $31.79). A sale running thru May 12th discounts the game’s prices by as much as 50%, bring the unlocking price down to between ¥1,200 (about $11.22) and ¥1,980 (about $18.52) depending on the game. After the in-app purchases return to their regular price, Amazon will be running a second promotion, between May 18th and June 17th, which gives customers 25% of the in-app purchase price back in Amazon Coins.
