The original was published by Flying Buffalo, entitled
"Imperialism""

     Overall quality: poor, four map pieces (plastic
     encoated), uncoated die cut pieces, cards on stock,
     rules a prelude to the revised edition. I only bought
     this for "reference" purposes after I had the revised
     edition. As stated before, the maps were to be used
     with a grease pencil to mark in infrastructure
     improvements (Ports, Cities)

Grand Imperialism, second edition: Published by Gametime
Games, a division of Heritage Model, Dallas TX, copyright
1979: (Good quality)

     Mounted 4-part map: thick-cut, glossy counters
     (representing: Native Armies, Pirates, Money
     (Resources), Cities, Ports, Fortifications, and the six
     main antagonists represented by counters representing
     Albion [English], the Third Republic [French], the
     Empire of Prussich [Germany], the Garibaldin Kingdom
     [Italy], Confederation of States [United States], and
     Imperial Ranshu [Japan], plus my optional "Warlord"
     counters (they add to combat roles, but if killed, you
     gain no new wealth on the next turn when they appear in
     you home country). Cards on glossy stock with
     backprinted logo of Heritage Models.

     A simple game encompassing economics (build ports,
     cities, fortifications & units), attrition (for units
     entering jungle, deserts, crossing mountains), and a
     CRT. (Rules are four pages total).  The card play added
     a "luck" element, but also allowed players to gang up
     on someone doing too good to bring him down.
