If you liked BoZ then you will love Xenoverse. Battle of Z was a heavy team focused arcade brawler. Xenoverse borrowed a lot of what made BoZ good but cut all the really dry non suitable parts. This game still has multi player battles and the 3D free roam fighting. The combat system is much more in depth than battle of Z so you get an actual sense of getting better & better at fighting with your created character (or the main roster) where as BoZ once you learned the 1 combo the game has you were already at the wall
Xenoverse isnt exactly like BOZ but as i said it takes the things that were good about BOZ & merges it with the Budokai style. Lots of combat to learn & enjoy.
