Yoshida Addressing “Butt/Hip Sliders” and The Solution To Them:

[ItMe]

Or he sounds like someone who has been constantly asked similar questions about a limited character creator and game engine that he had nothing to do with and was forced to inherit from the previous development team to save costs. Barring SE putting all the money they're making from the game, back into the game, we're not going to see a game engine upgrade or added creation options. The reason he went for that answer is because it's the truth. The game is built on spaghetti code that was outdated by the time 1.0 came out and SE probably forced the current team to use it to save a buck on a gamble. Because of that, they have to balance how many characters they have on the screen with the amount of character creation options and other really stupid stuff.

Good point.
I feel like people tend to forget this.
