The problem we're facing right now is the issue with popularity. Feel free to hammer me on this: DBZ is more popular than both DB and DBGT, and by a grand scale. If you really want to see more characters appearing from the other two series, it's not going to happen easily. Since DBZ is the most popular and the most exciting, they are not going to take DB or DBGT seriously into development until they got their main point right (Hence the name "DragonBall Z Sparking! NEO"). Heck, they haven't even added Dr. Uiro in yet (I know he's a movie character, but he's still from the DBZ era). Other notable but remained missing fighting-type DBZ characters including the rest of Bojack's crew, Bardock's crew, Tullece's crew, Coola's crew, Jinzoningen 14 and 15, Bio-Broli, King Cold, Kibito, Kid Vegeta, Young(?) Nappa, separated Hildegarn, Yakon and other Babidi's monsters, other Kaioshins for the flash-back battles with the original Buu, Veku, Fat and Skinny Gotenks, Robots from the Big Gete Star, etc. If they add at least several of these characters, that's when Piccolo Daimao, Gyumao, Chi-chi, Kid Kuririn, the Tenka'ichi Budokai participants, Cyborg Tao Pai-pai, Red Ribbon Army officers (especially Assistant Black in his robots), Pilaf and his henchmen in their robots, Yamcha with Sword, Baba's warriors, GT Son Gohan, GT Son Goten, GT Trunks, GT Vegeta, GT Son Goku, GT Kid Son Goku, Baby before possessing Vegeta, all Evil Dragons, and other characters will show up. In my opinion, my theory above sounds like something that was thought up in the world of boredom, but hey, they still have a long ways to go before adding more DB and DBGT characters.I am not really sure if kid Kuririn is going to be in the game but..
Lets just hope Piccolo Daimao is in. I mean they must put every
Budokai character if they hope this game gets the first place right?
Like I said, hammerings are welcomed.
