4. be able to design your own armor (the armor would have the same stats, just look more personal)
5. be able to change your char's looks, so if you decide that you want, say, black hair and not white, you can, and make it so you can make your charectors alot more personal, for instance; eye color, hair length, skin color, face choices, and starting clothing
6. what I think would be really cool, design your own furniture ^^
