I was waiting to finally put this out since all of the DLC is out.
So...coming from a fans standpoint,I love this game.It's rooster is about meduim and overall good story.
But,they could have added a few more main-ish characters/transformations.Including Majin Vegeta,Super Buu(With SSJ3 Gotenks/Piccolo and Ulimate Gohan),Gogeta SSJ1(From Fusion Reborn),Andriod 16,Baby Vegeta,Uub,Janemba(2nd form) and Imperfect Cell/Semi-Perfect Cell.That's only naming a few.

Now a few other things,besides having the Xenoverse story have separate Saiyan saga-Buu saga/Beerus saga to give the newer fans more history.Or having an offline tournament,which also includes difficulty levels increasing each time you win, where all the opponents are random and you can either win Zeni or a random item.

Now for some negative stuff.It gets boring after a few good hours of playing,leaving you only to grind or get destroyed in online battles (either from hackers/cheaters or Super Saiyan Spam).I would say something about the servers being bad but they pretty much fixed it so.

Now for recommending.If you're a huge Dragon Ball fan,it's totally worth the buy.Only if you're ok with some (maybe alot depending on RNG) grinding,and replaying PQ's to get the highest rank.
For the second recommend.If your new to Dragon Ball,I would maybe read up on the history/story and wait for it to go onsale or something,but if you want buy it and enoy it.

Well there it is,I hope you found this recommendation good and helpful. :)
