I decided to start with OpenGL implementation. Since I want rendering to be separated and it would be good practice. The planning now is to have followed the OpenGL videos from the Handmade Hero series. So that in the new year I can start looking into some console porting. Maybe even before the end of the year.
It’s clear that we get to the last bits now for the base of the engine. Having extra time in the weekends and soon on workdays I can speed up the development a bit. It’s just for 4 weeks or something, so I have to make the best of it while I can. That hopefully enables me to start the actual game development a month or two earlier than it currently would.
