CryENGINE 3 Independent Developers Platform
We want you to make games with CryENGINE 3 that people will want to play. We hope that your work will lead to a product you can commercialise. If this is the case, before you can sell your work or your game, you must seek a development license for CryENGINE 3. We’ll offer a royalty-only license model for Independent Developers, where Crytek require only 20% of the developer’s revenues from the commercial launch of their game.
CryENGINE 3 for Indy Studios & Downloadable Games
Crytek has attractive options for smaller games built with CryENGINE 3, with shorter development timescales. If you want to move your game onto platforms other than PC, or you need access to CryENGINE 3 source code, please contact Crytek to find out more about our licensing for Independent Studios.
That doesn't mean it would be the ultimate solution, but maybe some other good engines out there have similar offers, don't you think? (I am an ignorant on that matter though, are there many engines availables?)
