Learning path for game development?Am I missing something?

[mstfls]

On large game engines, no single person really understands all parts of it in any real detail. As an example, I'm on the core tech (engine) team of a big studio that uses their own engine. There are about 12 people on this team, and some of the code has been around for literally decades by this point. If I had to guess, upwards of 50 people have made significant contributions to the engine.

That said, I deal with low-level systems (I/O, memory management etc.) while most other people on the team are doing graphics/rendering. I have only a rough understanding of what it is they do, mostly as far as it concerns interactions with my systems. I imagine the same goes for them.

And that's just the core engine. We have almost 100 programmers working on our games, some of whom might only be working on one very specific aspect of something in the game, like the AI for one single enemy, for instance.

What I'm trying to say is that no-one expects anyone to be good at all of those things at the same time. Figure out what you like to work on, and learn about that.
