Here's my impressions after five or so hours-
Pros:
Character customization is really fun and diverse.
Racial differences actually matter, different animations and styles of attacks, racial divide of physical attacks versus ranged attacks.
A lot of content for a Dragon Ball game, a good amount of content in general.
Tons of people online/the game world feels really populated, you'll find a ton of created matches.
360 version is stable framerate wise, no chugging or droppage.
Story is simple but endearing, fix the past and fight the people fucking up the past.
Cons:
Competitive multiplayer is a joke currently, way too laggy and shit just doesn't feel right.
You can only have one character created at a time, there are more character slots though*.
Servers are spotty and you'll get disconnected randomly.
Framerate chugs in the hub world because of so many players being present, no framerate issues or chugging during combat though.
Takes a bit for you to feel more powerful/for your upgrades to matter.
*You collect Dragon Balls randomly throughout the game, I believe you can wish for a ton of money, attribute points, or another character slot
This game came out at the perfect time, not much else for a while gaming wise and its a contender for best Dragon Ball game of all time.
