As far as I'm aware, there is no standard edition of the game, but £13.67 is a great price and the cheapest deal we've ever seen for Tales of Xillia 2. Don't forget to use the discount code too.
This edition includes a steelbook and a CD of dev-selected music tracks. I really enjoyed the original game and have been tempted by this one for a while. Well, when I can find a spare forty hours or so to really lose myself in it that is. Unlike many JRPGs, the action ditches the polite turn-based battles for real-time attacks with you switching between party members on the fly and working with specific partners to unleash unique combo attacks.
