My friend makes fun of me for liking Java, php and the fact i like coding OpenGL instead of using game engines.

Where would holy devrant stand ?

Do what the fuck ever you want

Do clean code on whatever language/tech you want...

I have never used opengl but i loved making my own game (engines) with graphics libraries. So I understand you completely. I also like PHP and I do C# instead of java.

Code in the languages you need or want to code in. They all do what the need to do at the end of the day or can be extended.

Make what ever you want, your empty txt file can become ANYTHING. It's almost like a god complex but we control the computers and servers of the world.
