Do you like jrpgs? do you like a deep story and characters? do you want to play for 100s of hours in a giant open world? Do you like anime? Sexualized anime characters doesn't bother you? Have you played any Xenoblade game? Are you ok with a battle system that evolves while you play? Are you ok with decent graphics with some beautiful landscapes? Are you fine with Welsh voice acting and not having perfect sync?
If you say YES to any one of these questions buy the game.
