I recently asked and self-answered a question on main What was the first arcade game to use a microprocessor instead of discrete logic?
In the comments, discussion started on what the definition of "discrete logic" and "microprocessors" are. Having left the question open ended, the line is quite fuzzy. I initially answered the question drawing the line between TI 74XX series of integrated circuits and an 8-bit microprocessor like Intel's 8080. Since then, there has been discussion of additional chips meeting the "microprocessor" criteria. Acknowledging this, I added an additional answer of a game that technically pre-dates Gun Fight and the explanation in my first answer.
In this case, were two answers appropriate? Should I have consolidated the second (newer) answer into my first answer? When is it appropriate to provide multiple answers?
