None. I have never used an engine. All my projects are coded from the ground up.
Yeesh. Good for you dude.
Thanks. I even went to the trouble of building my own resource editor and compiler that creates my own custom binary resource files for my games.
You're Cool Man!
I kinda like that my games don't need 100-800mb just to play. None of them have yet to exceed 300kb in size, yet they all come with graphics, music, etc. Crazy stuff...
