Made an account just to make this post.

The things I'd like to see most are:

1. The background stories from all-ages Aegis, I'd like to learn more about the characters.
2. Piggy-backing off 1, I'd love if they could bring the light novels I heard about here in some fashion (Even if it was just a digitally translated version, though I vastly prefer physical!).
3. Gold rushes.

If we're talking about ultimate wish-list content... I do like story stuff. Character bios, character interaction scenes, story missions that advance something resembling a plot. I realize this stuff isn't really a focus in these games but it's the kind of thing I'd like to see.
