And in most medias in general, most of the time when i look for games or comics or books on elves i have to look back what was done decades ago. Even in the last decade there is nothing to be found.

In the meantime all other big fantasy races get showered with content every years and sometimes months. Why are elves being ignored and forgotten like that?

Hobgoblins (as distinct from goblins) are rare. Slaad are rare. Hobbits are rare. Treants are rare.

Elves are not rare. They’re the third-most common fantasy race after humans and dwarves, and the only reason dwarves beat them is that is because of Dwarf Fortress and its followers.

If you want a game or games or other stuff about elfs, why don't make them yourself?

Not trying to sound like a douchebag. But seriously, some other creators may not have ideas/inspiration to create something related, others may not like people asking for stuff out of the blue (specially if expected for free), and who knows more.

But if you want elfs in games. Perhaps you  can try to make them yourself (or with help of others from the same elf-related niche.I remember there was another user with the same king of post). There are several easy to use game engines if you lack coding skills and I'm sure that there may be free assets you can do and some hobbyist willing to give a small hand or sort doubts for free.
