Star Noir operates under the fiction that an FTL drive works. To be specific, Sonny White’s implementation of the Alcubierre Drive works. In Starships, it makes very little impact, except to limit the places from which a ship may escape. I assume that stellar objects are not all known, so there’s a strong risk that a ship jumping into warp might run into one of those objects. Combat is therefore fought at “normal” speeds where Newtonian physics applies.
But what happens if all the objects are charted?
The rules for FTL are so different that this is not really a Starships scenario, but what I refer to as “one page rules” — a game stripped down to just the key mechanics. As a result, this scenario can be played without referring to the Starships rules at all.
(I expect that any One Page Rules will be a simple novelty. The usual “beta” warning also applies, of course.)
