I've known about this game for a while now, and although I like the concept I'm worried about the execution. If they do it right this game could be a huge success. I would love being able to explore the Dragonball universe.
Also, the only races are Human, Namekian, and Majin. It makes sense from a lore perspective that Saiyans aren't included since they are extinct. But Majin as a race? I wasn't even aware they were a race, I thought Buu was the only one. And wouldn't the Majin be way more powerful than humans and Namekians? I don't know.
The game has a lot of potential though. I'm sure down the line we'll see more races, like maybe "Android" or "Tuffles". And that would be awesome. I'd love to play as an Android.
Anyway, check out this
