If a tournament consists of 500 games and an All Access pass costs 15€ (149:-), the price per game is 3 cents. The price of the access-pass is set low because tournaments know that not everyone is interested in every game, but also to leave some room for mistakes that happen when a club or organisation is involving with technical stuff such as cameras and networks.
All Access gives access to everything that is live streamed from the tournament, sometimes one or two games have problems and buffer, or the camera man gives a bad opinion, or something really exciting happened and the camera forgets to turn the camera. It happens and it will happen in every tournament.
There is always an expiration date on access-passes, this date is when the replay won´t be available anymore with the access-pass. The date is stated in the confirmation email.
