Having a good time will also likely mean your games are strange - misshapen, erratic, half-formed, weirdly over- and under-developed at the same time. You will have to mutilate your way through the canon of design. A lot of the things you take for granted about the form will turn out to be boring, or hard to implement, or not fit with your own process, or you might feel like chopping them out for whatever other reason. Meanwhile the most trivial things can grab your attention, draw you in. I think that’s fine. I don’t think anybody needs more well-balanced games - that’s the worst of all backhanded compliments, next to “diligent”.
