I did ask the question "What is a Gateway Game" and I got a pretty good answer, but not good enough to tell me whether Monopoly, Race for the Galaxy, Ra, etc. are Gateway Games, though the comment stream following the accepted answer helped me get closer to determining what a Gateway Game actually is. I guess I could take @AlexP's suggestion and ask a new question, "What makes a good gateway game? Please provide some examples" and see what happens. – Joe Golton Jun 14 '12 at 19:22
