Biggest problem I have with a movie like this is them trying to make a movie out of an endless sandbox game. If a game has a definitive end, then sure it's fine. Just look at the Fallout show and Sonic movie.
Imagine if for some reason The Powder Toy suddenly became a huge thing and they decided to make a movie out of it. Where do you go while not being lame? That's how I feel about this upcoming film.
