I've played a number of children players and they of course don't look any bit like children, more like adults [obviously] I think that they should have 4 model setting for age to choose from in future versions:
-Child [I can't see playing a little Ylian, or Dwarf boy when he has a full beard, and actually feel IC!]
-Teen
-Adult
-Elderly [hunchbacks, gray hair, wrinkles, etc]
For what i know, these can apply to all of the races, (maybe not the kran for elderly) but for most. I think it will make the experience of playing a different age other than somebody in their 20's and 30's which is the age that the models seem based around in PS in my opinion. I think that the creation of the age in the model should also impact the stats of the character, say an elderly character would have very low strength, endurance, and agility, but make up in intelligence, will, and charisma. I'm not sure if this has been posted or not before, but it's my major wish out of this game.
