For those playing the game in NA & EU on PS4 & STEAM, there's a potential issue worth monitoring, especially for those who haven't purchased the game.
The Happy Wedding Costume Set 1 just became available, and NA & EU people are noticing the costumes are not available to purchase individually on PS4 & Steam (this was already an issue for DoA5 on Steam).
The below image is currently featured on the English-language DoA6 website.
The image's counterpart on the JP site lists the costumes as being available for individual purchase on Xbox One & PS4, which is currently reflected on both the JP & HK PSN storefronts.
------------------------
My intention was to wait for a price drop on the base game, before considering a purchase, but that's completely off the table, if NA PSN users won't be able to purchase costumes individually.
