When I started my current character I made sure to play to my Charisma stats. So he wasn't as attractive as he is now. As his Charisma grew so did his changes of looking more handsome. When he hit attractive he changed to more Adonis like body and looks.
What bothers me is people who don't have the Charisma to back up their looks yet looking amazing. And I'm like huh? How is this happening? I seriously believe that a person who does not have the Charisma should be looking amazing. Specially iut of chargen. I can apply this to any stat. But its the descriptions that kills the immersion for me.
