Being a relatively new player (been playing less than a year), I feel there is still so much for me to enjoy. For example, I haven't done anything at all at the Gold Saucer yet.

But I can definitely imagine that after years of playing and having done everything, things would get dull waiting for new content.

To be honest, I was very surprised by the lack of meaningful content to the newest patch.
We got a couple new dungeons and Aquapolis and some new recipes. (Being a crafter I am really enjoying the crafting aspect of the patch, but...)
The quest content was very short and, although moving, left a lot to be desired.
It was over in a couple of hours (and yes I watched all the cutscenes).

The new dungeons were not challenging at all. Except for Weeping City which was challenging the first two times going in. It's still fun, but it's easy now and the limit at loot gives us little reason to go several times a week.

Aquapolis is interesting, but the fights are too simple, always the same, and because it's random chance it's not challenging.

I log in because I want to be a better crafter and be the type of person who can craft almost anything for her FC or friends.
I work at home in the countryside, so it's hard to get out and meet people frequently. I log in also to just chat with people.
