I am really glad that I am huge Ninja Gaiden Fan and love this game more than DOA. Every Character in Ninja Gaiden have the same number of costumes doesnt matter female or male but in DOA the females have more costumes than males [...]
Ehmm... actually this is not right XD
Every NG has a disparity in the number of outfits between Ryu and the other characters, with the Dragon ninja having always more outfits than the rest of the playable characters.
In
NG Sigma Ryu has 3 outfits while Rachel has just her standarad one (on the other hand, she can be used with 10 different hairstyles):
NG Sigma 2:
NG Sigma Plus:
NG Sigma 2 Plus:
NG3: Razor's Edge: (that anyway is the more balanced in this matter together with Sigma Plus).
However about the DoA outfits, would be meaningless and wrong for Team Ninja stop to give new outfits to the girls, overall because there are the most popular and used characters of the series: instead a more realistic wish would be to create DLC packs not dedicated only to the girls like happened in DoA5, rather to male and female characters, creating packs including outfits for all the characters or just a part (for giving more variety like the sport one or the casual), but always including male and female characters. After many requests of this kind TN is currently acting exactly in this way, so I'm fully satisfied for the outcome
About the swimsuits outfits, I think that 4 are more than enough for a game of DoA part of the fighting series me too, anyway Marie Rose lack of a swimsuit and TN surely will decide to include it inside a pack with swimsuits for the female roster (contrarily to her Santa outfit that very likely will be her C5 included in her update for DoA5U).
So I'm already expecting a new Swimsuit DLC pack sooner or later, but if in the meanwhile Team Ninja will give us also outfits completely different and for all the cast (like I repeat they are doing now) I will not have problems with a new swimsuit in the girls' vestiary, also hoping that they will use this circumstance for giving a new kind of costume to Christie, Lisa and Tina.
