In most modern Z-machine interpreters, the Stationfall status bar will show something like
Deck Twelve Score: 0 Moves: 5066
Moves: part really makes no sense when you think about it. It is in fact not showing the number of moves, but, according to the game, the “Current Galactic Standard Time (adjusted to your local day-cycle) .”
The original Infocom interpreters all seem to display this as
Score: 0/5066, which make a little more sense (well, except that you might think that the time is a max score). I guess this is hard coded in the interpreters, at least I can’t see anything in the source code that would explain it. The standards document does mention “time games” and “score games”, determined by bit 1 of ‘Flags 1’, but offers no explanation for this particular behaviour.
