Thank you for your inputs. It is encouraging to know that there are some old grognards who remember these types of games.
Some information that might help jog memories (mine is hazy; it has been 40 or so years ... )
As I recall, players would be assigned a country (mine was Taiwan) and a limited amount of "resources" in points to "spend" ... military points to buy equipment, industrial points to build industry / technology, iron / steel / ores to build industry or trade w/ other players.
If I recall, you would be advised of adjoining country's leaders and contact info (e.g., as Taiwan, I was initially in "diplomatic" contact w/ China, Viet Nam, Korea, Australia [and these players were in my area; we met a few times over pizza and beer to discuss strategy, alliance, trades, etc.]).
As the game proceeded, you would in one way or another learn other leader's info, be able to contact them for trades or alliances, and build your country. All of this was done via snail mail or phone or meeting, and behind the scenes the moderator would oversee the whole game and send updates via snail mail. You could also send a message to (e.g.) Canada via the moderator, if you did not know that player's contact information.
It was (to me) a more detailed form of the game Diplomacy. Some people have suggested that I am misremembering that game, but (as the ad shows) this was in fact not Diplomacy.
I know that there was more than one "instance" of the game running, and that some players were involved in more than one game at a time. I also recall an announcement of the winner of instance III (or maybe V).
Anyway, I hope this information might reach someone who recalls playing this game, or even the creator / moderator themselves ... all of us would be in our early sixties or older by now, if still kicking. Anyway,
Thanks for reading!
