Getting a mount

[Niwashi]

The pet peeve seems to be that in advertisement they didn't include be lvl 20 AND some quests to do

The caveat listed on the CE is:
* Players will be able to ride mounts once they have reached level 20 and have obtained a chocobo.

Since HopeXIV did apparently notice the "once they have reached level 20" part, I'm not quite sure how she would have missed the "and have obtained a chocobo" part that's right there in the same sentence. That indicates right there they have to do the same thing as non-CE players to obtain a chocobo, and obtaining something in an RPG typically means completing a quest, (unless an RNG drop is involved, which luckily it's not in this case).

You get a chocobo the same way as everyone else, just like the CE ad said. Then once you have a chocobo, you can use any mounts you have, including the Couerl and Fat Chocobo that the Collector's Edition provides. It's those two that people without the CE don't get.
