C3i Magazine was created by Rodger B. MacGowan in 1992 as a house organ for GMT Games. (The title comes from C³I, a military acronym for "Command, Control, Communications and Intelligence").

In his introduction to the premiere issue, he stated:

C3i is devoted to GMT Games. C3i is not a review magazine. We want to provide you with articles that will inform, entertain, add to your perspective and instruct you in your enjoyment of GMT games. But we have no intention of making C3i some kind of publication-Cyclops with a closed mind. This will be an in-house magazine with an independent vision and perspective. We will talk about the rest of the hobby in a constructive and friendly manner. C3I will be inclusive and not insulated from the hobby and industry.

C3i will add new life and excitement to your collection of GMT Games. The Game Module Insert in this premiere issue is for Hornet Leader and covers potential future conflict in North Korea. Included in the Module are new cards, counters and rules. The C3I Module Insert will be a regular feature of the magazine.¹
