How do you create your character?

How do you create your character in video games? Mostly talking about MMOs but it also can be any game with character customization.
What class do you pick, what decisions do you make with your character, and do you roleplay as your character?

Most of the time I try making my characters look like me, I never do anything crazy looking or weird. I sometimes do try to roleplay as my characters for example if I am a priest class in a game I would comfort and help everyone I can or if I were to pick the warrior class I would play recklessly and be arrogant. I never made a character of my opposite gender it just feels weird to me and I don't want to catfish people haha.
