Adventure Time: Pirates of the Enchiridion might be appealing to a younger audience that wants an RPG without too many advance systems to over-complicate things, but if you're looking for a deep role-playing game set within the land of Ooo, you'll be sorely disappointed. On top of that, all of the performance issues with the Switch version make it incredibly difficult to recommend.
One Piece: World Seeker tells a surprisingly well-realized story that fans of the series are sure to enjoy, but only if they can make it through repetitive and frustrating gameplay. The talented voice cast and bright, popping visuals are a treat, but it does little to revolutionize the open-world adventure genre. If you aren't a fan of the source material, World Seeker is hard to recommend, but lovers of the Straw Hat pirates will find an enjoyable story buried under a lot of mundane gameplay.
As a fan of 3D platformers, I wanted to like this game. But in its current state, I find it very hard to recommend and I'm not sure performance fixes would make it all that much better.
