Great stuff!!! Finally some actual information about what they are planning to do. I particularly am interested in this specific comment:
Vault:
In the future of Chaotic Throne, will players receive broader options to personalize their characters' appearance?
JHH:
We also think that being able to personalize and customize your own character is an important part of MMORPGs. We cannot implement many changes at this time due to the planned graphic loads but we will definitely add more items and systems for customization. We are thinking about changes in items rather than facial changes for now.
