Question: I am the only developer, created a game and going to sell 1,000,000 copies. How many licenses do I need?
Answer: If you create a game you don't resell Particle Universe as a particle engine, but just make use of it in your application. You are allowed to include the runtime plugin as a dll or statically link it with your application and you may include the (changed) example scripts and the textures. You are not allowed to include the editor or the atlas texture tool. If you are the only developer and sell 1,000,000 copies of your game you just still need 1 Particle Universe license.

Question: What is the extended download and do I need it?
Answer: The extended download makes it possible to download Particle Universe during a longer time. It is a service of Share-it, which handles the payments. I think this is a worthless service to get more money. You can receive updates through me (spookyboo), even if you loose your copy of Particle Universe (but don't loose you share-it purchase id).
