The first step is to learn 'what is a cell'. With this tutorial I want to show you how to create your own templates - of any size, because all modern RPG-Makers accept and handle sprites of any size. And yes, that is similiar in how far you would be able to go in real life without knowing how to multiply? A basic shopping trip would become a problem. Limiting yourself to premade templates is the same as saying 'I only want to learn addition and subtraction, I have no need for multiplication'. Because the engine itself doesn't use such templates, it uses mathematics. Templates are crutches - bad crutches to be precise, because if you need a premade template then you're drastically limiting what you can do with the engine. And they don't even understand how limiting that is.
Time and time again people who want to create their own sprites are asking for pre-made empty/framed templates because they can't work without them.
