There are actually quite a few different animations out there, like Goldchocobo's and Tailgate's animations. Those are free for download, and I believe Goldie has made multiple.
Same goes for items. You can make your own, or download them. The largest is the Legendary Items pack, and it has a ton of items for you to use in it.
While I believe that animations should still be left as optional downloads (as you may not like one you download, so you can turn back to the original), I would like to see quite a few more items just downloaded with the game by default.
