Pressure Gauge suggests, by its name, some mechanic of managing pressure or rising risk, a design device several early-80s arcade games explored under different thematic disguises. There isn't, however, enough reliable documentation to pin down its exact genre, development, or release date with certainty.
Faced with that lack of certainty, we prefer honesty: it's one more piece of the era's scattered catalog, of interest to the curious collector rather than a well-documented chapter of the medium's history.
