In the words of Herr Teuber:
"In the summer of 2006, I sent 2 prototypes for a Catan dice game to the Kosmos Verlag. The first prototype was the easier one to play, while the second prototype, following the Board Game closer than the first one, was a little less accessible for people who don’t know the Board Game.
"My favorite was the second prototype, as it offered more of the Catan gaming experience and, therefore, more competition and interaction. In the end, the Kosmos Verlag opted for the more accessible dice game.
"I could understand this decision, but I’m pleased that on this page I now can offer the second prototype, under the name of 'The Dice Game Plus,' to all those who like the Dice Game."
