The way it is supposed to work is 3 versions below. For example, Pop'n 16 PARTY added Jewelry Girl, which is a CS exclusive that was new on 13 Carnival. It also added Kanransha, which is also from 13 Carnival (there are many more, but these are just popular examples). Pop'n 17 THE MOVIE will bring over songs which were exclusive to 14 CS, since 17-3 = 14.
However, sometimes songs don't get brought over / get delayed or sometimes they get brought over and removed later. |
