If you are building a commercial PC game, regardless of price, you can begin developing your game immediately after downloading from the www.havok.com/tryhavok
site. During development, you can evaluate, prototype, and even publicly demonstrate your PC game, subject to general restrictions in the download agreement, with no further involvement from Havok.
Prior to publicly selling your Havok-powered commercial PC game, however, please note:
If you plan to sell your commercial PC Game above a retail value of $10 USD, (or equivalent amount in other currencies based on prevailing exchange rates at the time of launch), you must first request a no-charge PC Game distribution license from Havok at www.havok.com/PCgamedistribution
, prior to retail release of your game. This PC Game distribution agreement is required to ensure you have complied with Havok logo, copyright, and attribution requirements, and that your application is a PC game (commercial non-game application distribution is not allowed). There will be no fee associated with this because the license fee has been covered by Intel under a commercial agreement with Havok.
If you plan to sell your commercial PC Game for a retail value of less than or equal to $10 USD, the PC Game distribution license is NOT required from Havok … knock yourself out!
