There is an Anakin Skywalker Sim already on the Exchange but it's not really that great, I think. It's poorly implented and looks nothing like Anakin or even Hayden Christensen (the actor).
I would like to see 2 separate Anakins, both good and evil, since Anakin becomes evil (Darth Vader) in about the middle of the movie.
The first Sim would be Anakin as a good man, but of course not without character flaws. He needs to have a scar on the right side of his face, like he does in the movie. A custom skin could likely be used to make the appearance of his mechanical arm (his arm was cut off in Episode II). He also needs to be dressed like he dresses in the movies; try not to use any EAxis clothes and accessories, those just won't do. If at all possible, it would be nice if he could also have a light saber; I just don't know how it could be done. His facial features should bear a striking resemblance to Anakin Skywalker (Hayden Christensen) as seen in Episodes II and III.
The second would be an Anakin Sim as an evil man (Darth Vader), but before he completely loses his humanity and is transformed into the Darth Vader body suit. This would be nearly the same as the good man, so just use the same Anakin Sim as above, but dress him up like a Sith Lord, and don't forget about those evil-looking glowing red eyes, either! His personality traits should be somewhat different since he is now an evil man.
An upload to the Exchange or a fansite such as MTS would be great (or perhaps both).
Have at it!
Yes, I have WA 1.8/2.3.3, with the latest AwesomeMod installed.
