A King's Tale: Final Fantasy XV (Empty Clip Studios, 2016)
One of many Final Fantasy XV tie-ins to be released, this one was first made available as a preorder bonus and, after the game's launch, became a free download. A King's Tale is a side-scrolling beat-em-up with a few Final Fantasy twists - some enemies resist certain types of magic, you can do different combinations of moves to stun and juggle enemies (necessary for many of your larger foes), and all of the differing enemy types require different tactics to overcome. However, you also get some help in the form of three summonable allies who can be called in after you land eight hits without taking damage, and upon landing 24 consecutive hits, one can summon the Armiger to deal heavy damage to a single foe, as well as calling in your previously-summoned allies to do their own attacks and deal massive damage. The main campaign is short - it should only take you about two hours to complete - but a number of trophies and optional challenges will keep you coming back. If you enjoy arcade style beat-em-ups, give this one a try - it's a lot of fun and, as mentioned, is free.

Also of note: The film's heroine, Aki Ross, was slated to be the first computer-generated actress and appear in numerous future film roles, but owing to Spirits Within's financial failure and the subsequent closure of Square Films, that never quite happened.
