I'm an indie game developer. I can say that because I helped to develop a video game. It's publicly available now and you can download it for free. I was one of two people who worked on the project. Although I had to wear multiple hats, and had a bit of a hand in many aspects of the game's design, my primary job was to create the art for the game. Everything from character concepts, to animation, to lighting, to creating the textures for all of the 3D objects; was all my responsibility.
I can't say that I ever really set out to be a game developer. Many developers will tell you how they've been completely in love with games since before they can remember and were messing around and trying to make their own since they were in grade school or something like that. They will also say that they love playing games and may consider themselves avid gamers. That's not quite the case with me.
I love entertainment and somehow developing games seemed to be a good way of expressing that. The first time that it ever occurred to me to make a video game, I must have been about twelve years old. I had absolutely no idea of how to do it, and I admit that I didn't try very hard. I knew nothing of game engines, programming, etc. and basically just messed around with 2D art concepts until I gave up and moved on to something else. It was the idea of the game that I found appealing, and it's that same idea that came up in my mind again years later, after I realized that games had now become 3D and much cooler looking. I wanted to make one of those.
Despite the fact that I'm a game developer, I don't normally think of myself in those terms. I can't wake up in the morning and tell myself "I'm going to be working on a video game today" and feel inspired by that. The truth is that I am not interested in making games; I'm only interested in making my games.
In order to create a game (or at least a good one), you have to be willing to immerse yourself in it. I could only put that kind of effort into something that I genuinely like and feel passionate about and that certainly doesn't apply to all games. In fact, it only seems to apply to ones that I helped to come up with myself. But then again, that's why I'm an indie developer.
