An indirect sequel to
Xenoblade Chronicles, it's a science fiction JRPG in a world where Earth has been destroyed by aliens. You are a part of a large ship that left Earth as it was being destroyed in hopes you'd settle on a new home planet that's safe. You land there and find out that there are several problems facing both humans and the species inhabiting the planet you've landed on.
It features nearly everything you would expect from a solid role playing game, a main story, side quests, crafting, mechs (known as Skells in the English version), complex battle system, and more.
