It’s hard to predict what the plot of the movie will about. The video game is a sandbox environment which allows players to build and explore worlds with very few rules and regulations to determine how they use the worlds they build. There are endless paths for the film to take, and while we don’t have a story just yet, Rob McElhenney of It’s Always Sunny in Philadelphia was just hired to direct to the picture. Many people are suggesting it could have a similar feel to The LEGO Movie, which will actually share its producer, Roy Lee.
There’s no release date yet, but the earliest we would see the film is probably 2017.
