I want to become a video game develper I would like to know how it works

The first thing you should do is understand that designing a video game is actually pretty hard. It takes a lot of creative problem solving, advanced logic, and pre-planing. I used to program games as a hobby so I am really only familiar with simple games, I never really touched any real multi-player. Here's the basic (really basic, each step has way to many sub steps to cover them all here) check list. 1. Come up with an idea, it should be original in some way. 2. Write an algorithm, basically a flow chart of how the program will be writen, later this will be used kind of like an outline. 3. Write the core program 4. Design graphics and 3d models 5. Finish programing and scripting 6. Debug (there are always bugs) 7. Test, all games will have hidden problems so you should play through it several times and pay attention to the details. 8. Debug again 9. Deside if you like it enough to keep it, or trash it.
