Will it cost ??

Yes, all do. Some use private game engines like the creators of madden, some are free for the world and some cost but, there has to be a scripting language for the game to fully function. There are many and game engines are made from scratch, just a plane white screen that renders text and canvases. This is why most are private but capable. (sorry for the bad explaining and getting carried away)
