If you accidentally start character generation there is no way to cancel it. If I realized that I waned to read manual, change difficulty, select different game mode or even just exit after character generation is already started - there are still no way to do this inside game. I need either kill the process or finish character generation and kill it quitting.
Would be great if you could cancel it in any time: starting right from star sign selection and to the very last "What is your name?" prompt. Say by pressing [escape]. With confirmation if you think it's better.

Let's not go deep into re-rolling and star sign selection discussions... Is there any good reason why this feature is missing? It's just annoying and punishes players for nothing. Just a feature of convenience.

P.S. I'd like to have an ability to go back from every screen including history, talents and name but it's another story and RFE...
