HYPERSPACE DIPLOMACY II (Don Miller)
(1) STEVE AGAR in V&U 4 (September 1990)
One of the many variants that use the regular board, invented in 1972. The rationale behind this one is that each season a player may order a Link and/or a Separate order, this will either link the two provinces through hyperspace (thus allowing A(Lon)-Mun)) or separate them (preventing movement between, say, Lon and NTH). The rules seem to be fairly comprehensive, covering every possible situation that such messing about with the board could entail. Similar to Geophysical II in many ways.
