SWG Star Wars Galaxies Character Builder
A Character Builder program allows one to test out different sets of configurations for characters, so that they do not have to go through the in-game process of creating a character just to test out different combinations. It is especially helpful in getting the right mix of starting skills together so that you know what works best. Also you can use it to come up with the look of the character that you want before you go in-game.
A very powerful and full featured character builder is available at Skryer.
