I agree that the returns are not worth the investment if you are on a time budget. I'm retired so to me it's rare that the difference between a 2 hour set up and a 3 hour set up doesn't mean much. I prolly spend more time fooling around with hte game then playing it. By fooling around I mean setting up test games to experiment with different things under controlled conditions. I enjoy analyzing the game as much as I do playing it against another human. My analysis leads me to believe thatthere is no silver bullet in SP. No 'trick' that will ensure victory or cannot be countered in so way.
That is a big part of the charm of SP and why it has lasted an age in the fast paced world of gaming.
