I'm no expert on Naruto, but even I became a fan after playing through Ultimate Ninja Storm 4. There's so much effort put into the presentation alone that it's hard not to be engaged, and the gameplay (while simple) allows you to play across a massive roster of characters for some really cool looking and feeling battles.
On the surface, Unravel appears to be a simple puzzle-platform game that offers a moderate challenge, but has little in the way of impediments to progression. Scratch a little deeper, however, and it becomes clear that communicating the sense of place and atmosphere, as well as telling what is a very touching story is really the goal here.
Ultimately, Project X Zone 2 boils down to a healthy heaping of fan service for weebs, or anyone who's familiar with the franchises included. While the story can be slow and plodding, it also has some decent gags and a lot of self-awareness that helps drive each crossover encounter.
