How easy is it to make a video game?
I assume you don't know any programming, either, so a good start is to learn how to program. Then pick a good book about introduction to game development to see for yourself what you need to learn (keywords: game development beginners). Of course, you need to know about graphics, audio, basic AI (depending on your game). You also need to decide on the platform (desktop, mobile, web)? There is a ton of stuff you need to learn, especially if you haven't programmed before (learning to program can be a challenge in itself), but it all depends on how complex you want your game to be.Programming languages to consider are C++ if you are aiming for desktop, Java for Android, Objective-C for Apple devices, and alternatively you could also learn Python or Java. Another option, is to start working with game engines such as Unity. You could download the community edition, get a tutorial and start experimenting, while you learn how to program in C# or JavaScript for adding logic to your creations and compositions. Maybe, this is also a nice shortcut to getting something out relatively quickly, but that doesn't mean you are getting away with the things you are supposed to learn in the long run.
