Haven't tried a play yet, but I keep thinking of things to dirty it up...
Might require a STOP before landing; these aren't winged aircraft landing on long strips.
Also thinking of ships with special requirements: capital-sized but not so robustly built, say, large merchants that have slower speeds, and require a single 'DESCENT' to land.
REALLY have to play a few games before I let myself write up variants.
Thanks!
