It depends on what type of game you're looking for. I'ved played many games with elves in the casual market.
I also wrote one - where the main character is an elf, and she lives in a village of elves - some of the customers are elves. But its tags would centre on what the game is which is a casual game in a fantasy setting. I haven't used the tag elf because it didn't occur to me at the time to use such a tag.
