SureAI

On average, how often do patches come out?

I started playing the game when the English version came out, and have only experienced one patch so far. Do they come out at the beginning of the month? At the end of the month? Every few weeks?

I think "Whenever they are ready" sums it up best.

This is probably not most of the SureAI's regular job, so they do what they can when they can, or when its neccesary. Some "professional" publishers/developers dont bring patches out for months on end so I would say SureAI has a pretty impressive strike rate at the moment.
