They can apparently add some completely weirded out assymetrical hair and a lightning-bolt containing professor hairstyle but doesn't even bother to add long hair for female characters or anything else than wavy, spiky or parted hair for male characters.
Where is the downside? We get our hair, they get their cash, yay.
I'd love to see Wendy's hair in game. I'd pay through the nose to have it. $$$
I'd also love a proper copy of Ariane's hair, since the one offered at present is NOTHING like her hair in game. Not willing to pay *20 AUD for a hairstyle that isn't a patch on the one she has.
On a side note, I wish we could have Ariane's face: She isn't a pinhead like the current female player models, she's much prettier and she has blue eyes and lipstick.
