Quanta is different because they could still hype A wakening with the rest of the Power Rangers after World. Unicorn only really has one lead mech so it might not be a very good move to debut the FA Unicorn now rather than later. Not saying it couldn't happen but it's more likely that we'll get something from AGE instead.
Hard to tell, is AGE really popular in japan? That 3D was basically the Gundam AGE game --- Claims List is in quote."Let's just take it easy and agree to disagree when it's debatable, not when facts are involved.." - Me
Popularity is irrelevant to secret units, they're not used to promote the game. And 3D was no more AGE's "game" than World was Unicorn's. We got like the first seven episodes, it's hardly even had a chance to shine yet.
World was more 00S2/Unicorn's game and the rest was represented nicely while 3d was mired by butchered mech lists and such, seemingly for the sake of AGE units. --- Claims List is in quote."Let's just take it easy and agree to disagree when it's debatable, not when facts are involved.." - Me
Unicorn/00S2 didn't have anything special in World. They didn't have extra stages devoted to them, their rosters weren't particularly thorough or given special treatment compared to other series, it was just an ordinary debut. In the case of 3D, I would say they rushed to take advantage of the AGE hype at the expense of the game's content, even AGE's own, but then I would say the exact same thing about this game.
