The sun sign isn't everything though. Got to count in the ascendant, what sign is in the moon and - yeah.
Yes!
Well, overall I think the Sun sign is still the most important since it flavours everything about a person, but everything else tweaks a person a bit.
Ascendant: This flavours the person's exterior, their physical appearance, how they appear to others, the impression they give to others, like the shell of a Jaffa.
Moon: This flavours a persons emotions.
Mercury: This flavours a person's communication and methods of communicating.
Venus: This flavours a person's romantic feelings and how they romance.
Mars: This flavours a person's temper and sexual nature, and their drives and passions in general.
So, for example, while a person might be like a Cancerian, they could have the outwards impression and looks of an Aries, the emotions of a Taurus, the communication of a Gemini, the romantic nature of a Leo, and the temper, passion, and sexual drive of a Scorpio. Though Cancer will flow through all of these, being the Sun Sign. In this way, everyone is ultimately an individual, though we will share more than a few things with others of our Sun Sign.
The outer planets aren't as important in defining a person's personality as all of these. Also, given their slow orbit many people share them, so they affect generations more than individuals, you might say, so I don't pay as much heed to them, though they can be interesting to look into sometimes.
