It's not an option, but my vote would go to the fact that Telltale isn't talking to Lucas anymore to make more Monkey. Telltale wants to, Lucas doesn't. In some article they said that they don't expect to make another Monkey within the next five years
Oh, and the fact that the entire internet hates Telltale all of a sudden. They did some things wrong, and some of their games might be a bit rushed, and everything isn't perfect right now, but damn it, I still always have a great time with those games. There's a love for storytelling in those things that you just can't find in most other games.
