I would always come up with ideas for games and was making excuses not to start. So, when I was 13, I asked my parents for Blitz 3D for my birthday, then got started with that.
I started out by making a massive kitchen-sink open-world RPG with billions of features, which I worked on for 5 years and never finished, (for some reason. Then I scrapped it and worked on smaller things. I guess it's something I just kept doing since. I enjoy it. I couldn't imagine going back to just playing games and not making them.
