Would be neat if we could choose the age of our race on both ends of the spectrum outside of what we currently have.

I know plenty of people want to play older characters, as well as younger characters.

I'd play as a kid if the option was there. While their mannerisms/outfits were oversexualized, I thought that Elins were really cute in Tera (being a small girl and fighting with a gigantic lance/shield was charming), and I liked the option of making my character younger in games like Mobinogi. The idea of a kid fighting evil and saving the world has been appealing to me since I was little, I'd totally make some child alts.

Maybe there could be a relationship system somewhat like Ragnarok Online used to have where two eternally bonded characters could have/adopt a child character.
