I had to learn what was enjoyable about it by first burning out on what I didn't. This is a form of artistic journey that spans all mediums. Games often have many layers. If you don't really know why you're adding a certain layer, like a level design, or cutscenes, it instantly turns into a morale crusher that can spiral into ever-increasing scope(by way of "it's not good yet, add more"). And it's easy to fall into that with vague justifiers like "every game is better with more stuff" or "I spent time on it so I'm gonna use it". Eliminating contradictory elements removes morale crushers, but can leave the game barebones and underdesigned. The solution to that is to inject themes and principles that suggest the specific possibilities. Then you are simply including the elements that cohere to principle, which quickly "develops" the game out of the tech demo stage. In the blink of an eye it can go from nothing to a great game, if the groundwork was set up well.

Of course, most games are products, and products need product features, which take things away from the artistic goal. But if you can build it small enough, it can be a hobby :)
