Bringing this up because I was about to make a topic on it until I hit the search bar.
Not only do I want customization for DOA6, but the series desperately needs it. I remember back when DOA5 was still in development, they said they weren't putting in customization so that each character would be unique. "Alright" I thought. Then I learned what that actually meant. It allowed them to nickel-and-dime the customers endlessly. "Like this costume? Buy it for that character!", "Want to have this in a different color? Pony up the cash!".
If customization were in place, they could still charge you for clothes, but you would get much more bang for your buck. Take SCV for example. By far the best thing about that game was the CAS mode. The DLC packs were actually worth buying because mix-and-match, use them on any characters, color them, and create something completely new. You could personalize your own fighters, which would work well with the game. Imagine Tag Team, where you give fighters matching outfits. If they put this in the game and supported it like they support the costume packs in DOA, the options for character customization would be endless. Just imagine all the cool stuff people could make with an SC-like customization mode, only with more enhanced features. I could only imagine all the cool things people would make with this mode.
I'm not sure if there should be a full-on character creator though. There's pluses and minuses. the pluses is having the freedom to create things from your own imagination, and being able to show it to the world. But the minuses being that it kinda cheapens the value of the cast. SCV online was full of people making remake of various characters from pop culture. While seeing Cloud fight Abraham Lincoln online gave me a good laugh, I'm not sure if I want to see that in DOA.
