It's mostly dependent on the amount of time I have and what hasn't had much content recently. The next main story update will take the game into Act Three, so before that I need to get all the Act Two side content done - college, side girls, stats, family dates, etc.
Haha, well I appreciate the thought! But I'm not going to work on CK forever - I'm hoping to have it finished in another year, two at the most, and then move on to the next one!
This was my first game, so I'm excited to put everything I've learned from making it into the next one :)
