Addendum:I'd say Shadowrun and The Dark Eye also benefit a lot from character generators.
A Shadowrun character builder would help managing character generation points (if you use the system), money (that's even an issue if you the priority system of 3E) essence, bioindex, Ki Adept Powers, and it might be helpful for spell management or Karma management (Reputation, Total Karma, Karma Rolls - 4E might simplify this in some areas.)
There is a Character Generator for The Dark Eye.
Game system: The Dark Eye / Das Schwarze Auge, 4.Edition
Use: Free (GPL), downloadable, requires Java (6 recommended)
Producer: goneo Internet GmbH (???)
