I agree whole hardheartedly. I’m in the same position. I’m a solo code-centric game “systems” developer. I cannot call myself a game developer, because I have yet to develop one, but, I’ve developed plenty of game subsystems. Over the 4 years I’ve worked with UE4, My focus has been learning and developing networked procedural generation / player construction subsystems. Because I believe in-game Player Creations that can be shared and collaborately built is the future of social gaming. I also believe that High Density Modularity is the future of constructing Game Content. Only recently have I actually started working with combat game mechanic, which is at the core of a lot of action games.
