Fanboys will flame you for this post, but the reality is this company made a great game, sold a ♥♥♥♥♥♥♥ of copies, and realized there was no more money to be made. They are lazy as hell. If this is 'normal' pace for development, it would have taken them 50 years to make the release day version of the game.

This is what happens when early access games sell TOO well.
