I hear ya! Today, I mostly do it for fun on my old Apple machine. It is enjoyable to see what can be done. 1Mhz is actually quite a lot when one looks at the resolution and overall task to complete. And where to put it? Things like having the game run at 30Hz or 15Hz so more can be computed in game, in real time. Then, when it comes to drawing everything, often a simple screen clear, or page flip then draw does not make sense. Two screens takes too much RAM, etc... Single buffer, draw fast, only draw deltas, using XOR, all add up! Getting paid? I have done some assembly for money on Propeller chips, PIC, AVR, and the like. There are times in embedded land where doing these fun things pays off and makes sense. For what it is worth, a little fun can be had for income, but not much.
