At this point, even if I wasn't 100% sure on getting it, I'd pick it for 2 reasons:
1) I want to support this "style" of a DBZ game, because I've been wanting a solid 3v3+ DBZ game since Dragon Ball Z Legends waaay back on the PSX. That game was a 2D/3D hybrid and had a TON of potential to showcase the chaotic fun of individual fights on a single battlefield. This game feels like Cell at this point: a fusion of about 6 other games in the DBZ library, attempting to take the best things from each of them. I want to see a second version of this game, hopefully dropping the old console support and being nothing but PS4/Xbox1/PC.
2) I absolutely have to support this game after I heard about the official TS4 support through Ghost Nappa. For them (even if it was just through Sabat's efforts) to recognize some of their biggest fans is huge. I have to support that.
