I just created my character in Aika Global and I didn't start off as a child. I'm a grown man with a beard. That was the major selling point for me...

What a sad day it might have been for you..

Same for me and all of the newbies around me. 

If you really do like that feature, though....I'd reccomend Mabinogi. The game's not in its prime in my opinion, but I do have very fond memories of it. It gets massive updates like once a month and has an amazing storyline (IF you start at G1...it lets you start anywhere but it's bad about introducing what I think are the wrong ones at the wrong time).

It also has twitchy combat.

It's your pet/companion who starts as a child and grows as they level ^^
