I'm currently working on my new adventure game book going by the working title of Legacy of the Beast Man. I'm using the Game Book player program to make it and it's pretty good actually.
The gist of the game is this: You play as a guy who has been summoned for a continent-wide combat tournament where the winner gets the gift of immortality. However, the fighters, including you, are all shapeshifters or Beast Men, who can take on the form of a humanoid beast when fighting. Your character is a rare breed of Draconian, the most powerful Beast Man. It's your job to travel from city to city fighting in tournaments until you win the gift of immortality.
