@1:00 = "Ha! No one will know I'm a namek now!"
I'm a little confused... I thought I rememberred Dragon Ball Online having been a thing like several years ago. Though, I only recall Saiyans, Humans and Nameks being a playable race in that one... this looks like it has Buu-type guys, too. I'm just wondering if it's the same thing in a different stage of development or a new project altogether.
In a word where everyone is a hero or a chosen one, no one is. Heroes are heroes because they stand out and do things ordinary people can't.
It really depends on how it's handled. In my experience most of them don't really try to give you the "you're special" feel as much as they try for the "you're part of something" feel. Start up a character on WoW and you're mostly made to feel like you're part of your faction, as opposed to the legendary savior prophesized to that faction.
Or in DCUO, for the most part you're treated more as part of either the Legion of Doom or the Justice League. But you also have parts in that one where you're sent into instances at the request of one of the big-name heroes. You know everybody else is getting the same missions, but every dungeon and boss-battle is inside an instance so you're never running into other players while doing the really important stuff. So it's easy, while you're playing, to get into a feel of "yeah, I'm Superman's go-to guy. He comes to me when he needs things done."
Dragon Ball, though, doesn't really lend itself to an "us vs them" attitude, there aren't any real factions to speak of, and the fanbase would probably really want
to get to feel like Goku or Vegeta saving the universe more or less singlehandedly. An open-world DB RPG could work and be great fun... I'm not sure how an MMO would feel, though, personally.
