i think its a pretty cool idea. i stopped playing XI before the whole chocobo thing and always thought it was a shame.

i think if there was some way to rent out your chocobos to other players would be good to. the higher the stats the more they go for. and have the option to rent for certain time periods say 10, 20 or 30 minutes and stay with you till times up.. maybe kick or peck a few bad guys to death?

also with the odd chocobo and carriages about i'm guessing there will be some kind of auto travel involving them kinda like in red dead redemption.
