What does he mean by festival of bullshit?
'
Festival of Bullshit' is a catch-all term meant to encompass the range of excuses that Porn game developers use to explain/justify delays in the work schedule.
e.g. I've got family visiting, I've had to travel for work, My dog died, I've been laid up with a really bad cold, I decided I didn't like this scene so I threw out all the work and started again, etc.
On their own these reasons are understandable and sympathetic - where fans start to call foul is developers who make a habit of excusing delays repeatedly or consistently.
