I've been avoiding the hell out of this thread until I've played the game for myself but now that I have I can finally give my thoughts.
I fucking love this game. It's soooooo good!!
The story missions, wow! Something different! Towa and Mira were great and I loved every moment when they appeared and I had to go against them. Demigra was great and the final boss with him was awesome. I got a good 10-12 hours out of this story so I feel satisfied.
I created a Saiyan Character, his name is Cumber (pun on the vegetable Cucumber) and he was able to achieve Super Saiyan 2 with the help of his master Cell!

Also, I have to mention this, Dameon Clarke delivered what has to be his best performance of Cell ever! He was amazing in this game and some of the stuff he said had me pausing the game just so I could laugh. If you have Cell as your master, try and get a Z rank in a mission, you won't regret it.
The game looks great and the stages are fantastic (especially the city stages, they're not destroyed for once!). Combat is really good but kind of loose at times, I find myself missing combos sometimes but it's nothing too bad.
Character customisation is the highlight for me, I find myself playing as my created character over other characters because it's such a well made customisation system.
The game's soundtrack is the 2nd best DBZ video game soundtrack ever (behind Tenkaichi 2) holy crap it's good. There were some dialogue problems in the game, sometimes character's voices would be too low to hear, I'm not sure if this is a problem in the Japanese dialogue but it did occur with the English version.
I love how the missions are actually challenging and not unfair (except for that fight with Beerus and Whis THAT can go fuck itself) and the game encourages you to do side content so you can level up your character which is a great way to get the hang of things.
Overall, this is officially my favourite DBZ game ever (sorry Tenkaichi 2, I still love that game though). Huge props to Dimps, they've outdone themselves here.
