I play extremely casually anyway so it'd be hard for me to quit, only time I did want to quit early on was during the Titan unlock fetch quests that dragged on forever and looked out of place in an FF game, felt like I was playing a Korean MMO, luckily it's only a one time thing, once it's done it's done.
