Dragon Ball Xenoverse 2 has already been out for a year on the other major consoles, with the September 2017 release of the game on Nintendo Switch probably being the last one we'll see of the game. Because it's already been out for a while, we won't bore you with the details of what you already know from other game reviews and instead, we'll get to the brass tax of what makes this version different and if it's worth buying.
To be very clear at the start, this is the same version of Dragon Ball Xenoverse 2 that you've seen on console and PC with a few additions and changes. You're getting the full roster unlocked, including the dark Goku DLC addition from the Day 1 pack. All of the updates for character skins and appearances are included as well, so no need to purchase or update those. The downside is that you only start with four stages, which is the game's way of forcing you to go play story mode. You can do 1 vs. CPU battles or 1 v. 1 with a friend using the Joy-Cons, which work like a charm, but the best way to go is with a pro-controller.
The game comes with motion controls, but the controls are pretty useless as you have to do more than a gentle shift to get a move to work; you're better off with a pro-controller. Online play is a bit of a pain to work when trying to set up matches, but once you connect with someone, the battles are seamless. One of the biggest complaints people will have is that because the Switch is a system with lower graphics. You're not getting 60fps on the Switch, so there is some degradation when it comes to the fighting. The cut scenes look almost identical, although, you may notice the images being a bit more colorful and pronounced than before.
The Nintendo Switch version of Dragon Ball Xenoverse 2 works really well and it was nice having a fighting game with everyone I wanted unlocked at the start. That being said, there's really nothing new here to entice fans into buying another copy of the same game. If you already own this, pass on it. If you don't and you want it on a Switch, it's a no-brainer to pick up since you'll have half the game unlocked the minute you start playing.
