In CT, is the 6G acceleration limit caused by an inability of gravitics to compensate for any greater acceleration??
I like the old rule from White Dwarf, back before Book 4 came out, that says a ship's M-Drive pulls double duty maintaining the inertial dampening field and the acceleration of the ship. Under this rule, it'a all a matter of which way the subatomic particals spin, pushing and pulling.
Therefore, the G rating of an M-Drive not only describes the max acceleration, but it also describes the max G field within the vessel.
If a ship with a 3G drive wants to maintain a 1G field inside the ship, then 1G is devoted to that field while the ship can travel at a max of 2Gs velocity.
A ship with a 1G drive must have the crew strap in and be in zero G.
This makes for some interesting role playing situations aboard ship. I've always liked the idea of a 3G vessel having everyone strap in, going to a zero G environment, as the ship performs combat maneuvers at 3Gs.
Another, similar, alternate rule is to coniser the direction of thurst. A ship accelerating at 1G should maintain 1G inside the vessel, according to the direction of thurst. Thus, "down" would be toward the drive room. Consider this when you build the decks of your star ships (wouldn't work with most canon Traveller ship designs, except a vessel like the Azhanti High Lightning, where the decks are vertical to the equator of the ship, not horizontal with it).
Thus a 1G vessel has no problem. It accelerates at 1G, and that thurst makes the 1G field in the ship. When the drives switch off, and the ship coasts through space at present velocity, the M-Drive can be used to produce a 1G field inside the vessel--but this necessarily makes for course corrections, and the vessel can not travel in straight lines. It must always compensate for the time spent using the internal 1G field. So, if a 1G vessel were to shoot for the nearest gas giant, the ship's navigator would plot a course several degree "above" the GG's north pole, based on the use of the G field inside the ship.
I like this type of thing, too, because it adds some detail to space flight. Puts some meat on the believability bones, so to speak. Standard format Traveller ships require people to be strapped in while the drive is in operation, or the ship's construction would have the decks made so that the main drive was "below" ones feet. That way, walking is permitted.
Better drives can be used as a canceling effect on thrust. Thus, a ship with a 3G drive can use 2Gs acceleration and 1G inside the vessel to cancel the effect, putting the crew in a 1G field in the direction below their feet, towards the drive. Or, 2Gs can be used inside the ship, and 1G used for acceleration, so that the "down" position is ventral, and the ship still travels at 1G.
This is probably a bit persnickety for most Traveller GMs, but I think it's kinda cool to mess with.
Plus, maybe some lower tech worlds use drives such as these while higher tech ones use standard Traveller drives.
Heck, maybe you could start a war over one world going after the "inertial compensator", which is an almost magical device, allowing a 3G ship to move at 3Gs while the crew rests comfortably in a 1G field.
Just stuff to think about...
