After 5 years of being "JP onry", Square has decided to throw the rest of the player base a bone by offering up the redemption codes that came with the nation key chains when bought by a japanese player.
Odd since they have offered the nation key chains outside of Japan for a long time. Oh well... Their company, their country, their rules.
If they are going to do their own RMT, they should at least do it with useful items, rather than things you just BS around with. (ie the sceptors). This cap's concept was originally useful, but with all the different methods of transport and warp scrolls being 10 points now, it doesn't hold the sway it did 5 years ago.
