Veracity of numerical information

For any product, studios have to fill numerical informations (non exhaustively: Game budget, number of seats,…). Those informations are gathered to calculate the total amount of the sale. The LICENSEE swears on its honor that filed information is correct. If a fraudulent misrepresentation is proven, PERSISTANT STUDIOS may ask to have an immediate financial compensation considering the difference between declared numbers and reality.

The number of seats is given by the size of the production’s VFX team. If the production has no VFX artists or developer, and only uses outsourcing, it must purchase at least one seat.
