From what I've seen elsewhere, I believe it is 4-5 months between. Though they don't like to commit to a timeline.
Third Crisis is the first game. Third Crisis Neon Nights is the second game. 1st has a girl in a blue jump suit. That is complete. The girl with the blue hair is the second, and is early access meaning it is not complete.
Is there a way for the fire to burn the stump, or is it only the bucket?
