Cyber Lee,
If you want to make games with FPSC or any ther engine the best advice is to not get too complicated at first. Sure you can think of a plot or storyline and develop it but dont get too involved with investing too much time and effort into it and try to go for gold at your first game making attempts if you are new to gamemaking.
To be successful more importantly you will have to like the engine you use and decide if it is suitable for your use while you take best adavtage of what you have available. Use the default media (you can always replace it) to importantly learn about the product, what it can do and its limitations - Develop while you learn, start with some test levels and then something more advanced. Learn some scripting as you go it will help you. What you learn you can utilise later in real game levels or develop your main game idea and use test levels to do just that. Test out features and functions and skills before you put them into you main game levels.
Making a game needs a lot of work Yes.
