I have played standard once.. when i play the game these days i always use the extended..

it's fun beceause a character like kimarhi already knows how to use (use and steal, jinx) etc beceause he starts clos to rikku's grid.. it's also handy to have multiple characters with the haste or cure spel etc.. no big deal but it is fun to see lulu do a power break or you can make lulu your white mage and yuna your black mage
