One Piece 2: Pirate King Luffy's New Alliance? Oda Hints Massive Wars In Interview

Being able to pull out your Vita and smash some baddies into dust for a short amount of time keeps One Piece 2: Pirate King ticking along nicely, especially if you're grinding for coins to upgrade your characters with. These varied scenarios tend to last around 10 minutes or so each, and there's a heck of a lot of them.

 All Straw Hats as well as Trafalgar Law, Smoker, Tashigi, Aokiji and a few others also come with pre and post time skip variations featuring slightly different movesets, making the roster feel even bigger and more varied. Indeed, because the game's a lot of fun in quick bursts, coupled with the fact that the title sports cross-save functionality, the Vita version complements the PS4 release rather nicely – but you'll have to pay for them separately since there's sadly no cross-buy implementation.

In our new-gen review – which you should definitely read if you're looking for a more in-depth look at one piece online 2 – we've already described the game as one of the best looking musou titles on the market, and that's also the case when it comes to the handheld edition.
