I'm trying to find a book from my childhood. It was from sometime in the early '80s. It was a game in an oversized book (almost a magazine), kind of like a cross between a Choose Your Own Adventure book, a tabletop RPG, and a giant comic book.
The premise was a group of starship pilots and their various ships coming together to complete some kind of a mission that I seem to remember as almost a race. One of the ships kind of resembled a BSG Viper, and another one was a big sphere, a third might have been star shaped. Along the way, several of those ships were destroyed.
