I've been curious about game structure for some time now. Does everyone who is a game programmer come up with there own approach to structure there game, or is there like some sort of defined layout. to put this in prospective. Lets say a game programmer wanted to create a tiled map. Is there a specific way to do this, or does the every programmer do it there way.
There's no standard way of doing things when it comes to the implementation. It's like writing a book, there may be common overtones like the Monomyth (or Hero's Journey), but the story will be different and told in a different way for each book.
You could look at a dozen different games that had tile maps and you'd find a dozen different ways to implement tile maps. Just like if you asked a dozen authors to write a story about X, you'd get a dozen different stories.
You'll pick up more as you go and get better. This is why game developers still exist, it's an art that is different in each case.
