The first 4 elements available are earth, air, fire, and water. And the ai will create products for different combinations, for example: air plus air = wind. and if the element does not make a new element, the user can suggest an element to add to the game, the ai will then learn the new element, and use it in the future. And the combinations have to make sense, like air plus water = cloud. Not earth or gunpowder (can make element tree, how an element was made!)
