“Pipeline” made my head hurt, but not necessarily in a bad way. It’s a fairly heavy economic game that I felt was over before it had even begun…but I feel that way about most engine builders that I play. The components were of pretty good quality, though expect to set aside a couple of hours to both learn and play your first game. It’s also a bit of a table hog, what with the a formation of each player’s personal pipe network that they’ll be tapping for oil on a regular basis.
