1971 Gottlieb Astro, same layout as Four Square, which seems to be a pretty well respected game for it's rules/game play. An Astro just came up locally (seller has not responded, may be gone already?), and wondered what folks think of it. I know it's rare, so many may not have ever played it. I realize this will bring in the AAb vs. replay debate again, but just based on the game itself-opinions?
