First of all I got interested into computers at a young age thanks to Chriet Titulaer, who had a show in the Netherlands called "Wondere Wereld" (means: Wondrous World or Wonderful World in Dutch) in which all new technology was presented. Please note computers were a luxury when I was a kid, as I grew up during the 1970s and 1980s. When I eventually came to touch a computer I was quickly interested in programming these and started to experiment. Like everybody else in my time that was in the BASIC programming language, however the BASIC of that time should NOT be compared to the Visual Basic, Blitz Basic, Pure Basic, Free Basic, Whatever Basic we got today. As I appeared very talented here I quickly began to write simple games and eventually when MS-DOS became popular I switched by advice of my mathematics teachers to Turbo Pascal and began developing games there, and that was the start of a long road that led me to where I am now.
Due to the way I began my "career" in which we had no Unity, Game Maker or any other modern tools I was always in need to code my own stuff to get maps, assets and file management and other stuff on the move, I still prefer to work as long level as possible and to code the tools I need myself as much as possible. Although I now just use PNG files for textures and sprites, and .ogg or .wav for audio, I still use the JCR system now it's it's 6th full version of which I wrote the first version when I was a teen (and I no longer have the original version), the Kthura Map System used for my RPG games is also based on trying to be as self-reliant as possible. I may be a bit old fashioned but it does allow me a few of my own technical touches to things, I suppose.
