Customization is a big thing now a days...
Everyone wants to put their personal touch, their little flourish on something, and in video-games it isn't any different. Almost any game you can choose now a days will come with some degree of customization. In some it might be just picking a group affiliation, with aesthetic changes that may only be in color. In others you can pick races, where statures and shapes are vastly different. Or maybe you can choose your gear, make gear, or even dyes and colors. In yet others you can go as far as to determine to the millimeter how high the cheek bones will sit. All in all you better be ready. With all the time you have already invested up to this point in your new gaming identity, the one most visual aspect of you is yet to be done... How will you look?
Male/Female, Human/monster/animal/other, tall/short, skinny/fat... scars... freckles... hair... It can be quite a ordeal. I had a room mate once that literally spent over 4 hours getting the perfect face for a character using slider bars in a game. Is that necessary, no... is it how you will do it, maybe.. but either way you should be prepared that there are options ahead.
Going back to a previous post one of the things to consider is why you are gaming. Is this representation one of you? or who you wish you were? or just the most bad-ass looking thing you could come up with? Are you picking based on aesthetics or practicality? Is this character going to look different then the last game, or are you going for the same thing?

I personally always shoot for a redheaded female in any game when possible. I typically try to make them attractive, and "ladylike". I do this as a representation of who I wish I were, a continuation of a virtual identity that I have created. I sometimes will even make major choices such as race/class/ armor selection (all choices that have vastly sweeping game play impacts) based on what I think looks best. It was every wow players worst nightmare when you got a wonderful new drop that looked just abysmal. Did you want the stats, or did you want to not look like a walking circus? That of course is assuming you are playing a game where you don't have to make some of the heavy choices before you start. If you play Mass Effect, the you that you make in one game, will be the same you that you play in the next, and the one after that. That means you might not want to skip over that character customization screen using the random features choice, because its a mug you will spend a long... long time looking at. Here is a
jump-off to a video showing just a small handful of the millions of different looks you can get using the class, and character creator modifications for Skyrim, all choices you make before you even get to get into playing the game. Then you have Diablo 3, where the only
customization you have is sex, and then the gear you wear, as well as dyes you can apply to it. Then you can get into games like the Sims, and Second life, where customization is the name of the game!
