This is more or less how I got into programming, I just liked games and wanted to make mine! By the time that I had started to be skilled in writing code, I realised that I found it more interesting to build the foundations (graphics, physics, logic, AI, all those systems) compared to the game itself. It bothered me for quite a while that I didn't manage to finish anything very substantial (a lot of small jam games and whatnot, nothing commercial), but eventually I reconciled with the fact that I'm just interested in building the engine, not the game. And that's all fine!
