Obviously you can create you character however you want at the beginning of the game. I think it would be awesome if you could change you character in game. A barber shop and a tattoo parlor could both make incredible gil sinks and would just make the game that much more dynamic.
Another thing that would make this great would be the fact that there was a limited number of options at launch. This would allow us to make our characters more diverse with a system that would keep growing.

Different haircuts and tattoo would cost different amounts of course. There good even be quest built around you doing favors for the shops and them only being able to pay with here services. (tattoo marks, barber shop marks perhaps).

any way like the post if you like it, dislike it if you don't, oh wait you cant oh well just go to a different thread if you don't like it then.

Please add on your own ideas or whatever.
