Game making professionally is more like going all the way to playing a full piano concerto to a paying audience.

Sure you start by learning to play the piano, which is fun, but you also have to compose several pieces that people will like enough that they’ll pay to hear them, organise the concert, learn the specifics of public performance and so on.

The cycles were the pieces you compose are shit because they’re limited by your limited piano playing knowledge so you go back to learning some more only to find out you learned it all wrong hence your current technique will never be good enough so you have to relearn a lot of what you thought you already knew, is not fun and the having to learn everything else needed to organise the concert because you have to make the whole thing generate $$$ even though all that you really wanted was to play the piano, is also not fun.

For somebody working in a large game company, it’s the difference between a hobby and a job, whilst for somebody doing indie game development it’s the difference between a hobby and a business.
