Twin Dragon Trivia (DOS)
Twin Dragon was originally supposed to be released as a commercial add-on for Shadow Warrior. After the add-on had been finished, the publisher decided to cancel the project because the sales of the original game were not as good as expected. Some months pass and the rights for the add-on are finally given back to the original developers after a lot of complaining. This eventually led to the freeware release of the originally planned to be commercial add-on.
