6. Character Customization
As great as it is to have a defined character with a set personality and appearance, it would be really cool if Rockstar took a page from Saints Row's book and let us customize our character. In some cases, it's a lot more personal to watch your character grow and develop if you created them yourself. If that's too much to ask for, at least give us better customization options in multiplayer. Now, I'm not saying I want furries and lucha libre wrestlers in my free play sessions, but come on. Picking your ethnicity and whether or not to wear a hat doesn't count as a character creator in my book.
