I have been pondering about it in fact. Given that small ships in Starlancer had jump drives on a VERY short range, I am wondering if the Cruise is just stronger thruster or it is pseudo-jump drive.
Forget about Starlancer, it was too long time ago before and also these 2 games are barely connected.
And when it comes to technology topics, I recommend to keep this somewhere around.
Likely just powering down maneuvering thrusters and all other non-critical systems to divert more power to the main engine.
Granted, at best estimates, crossing the breadth of star systems would take literally months to years at a time (binary systems are quite large yo), there likely is some warping tech involved.
