Isn't it amazing how so many people (myself included) just completely glossed over this in the rules. Sure, it's a bit hidden. I guess MWM and LKW and Frank thought the math example in Book 2 was enough.
But, after 25 years of playing Traveller, do you know this is the first time I've ever even bothered with the math and mm conversion in Book 2 space combat. It alwasy
looked complicated, and I didn't want to mess with it. Besides, my first Traveller purchase was Starter Traveller, which completely skips that section of the rules in favor of Range Band movement.
Then MT comes along and changes the concept all together. The M-Drive can be placed into "overdrive" for short periods of time so that a drive rated at 1G can actually produce thrust of up to 3Gs for a short period of time.
The rest, is history. Things get glossed over. Things get left out.
For example, under Book 1 autofire for gun combat, if two other targets are close to the primary target, then they may be attacked by an autofire burst at the appropriate negative
only if the adjacent targets aren't using evasion. If they're using evasion, they can't be targets.
That same rule is regurgitated in TA#1: Personal Weapons of Charted Space EXCEPT the part about evasion is convieniently left out.
I see this happening with a lot of Traveller editions that are based on CT. Whole sections of CT text are cut-n-based to later Traveller editions (sometimes so that some people actually think the concept originated in an edition other than CT ... like skill cascades or the Experience Limit in MT), but important sentences are trimmed for space or not added from another section of CT rules.
The Escape Velocity rule is certainly a rule that disappears when you get to other versions of Traveller.
I remember when, years ago, I was reading an article about it, and my brain was like, "What's this? What do you mean a 1G ship can't land on every world it comes into contact with?! Rubbish!"
But, it makes sense. And, it also adds a dimension to the game that I find rather enjoyable.
The tramp captains with J-1, M-1 vessels have not only stick to the mains, but also look at the world size and starport class of their next destination.
If the world is size 8+, then hopefully the starport is Class A or Class B. That way, the ship can dock at the High Port, and business goes on as usual.
If the world has a Class C or less starport, the tramp freighter captain may want to skip that world.
Somebody has said this before about this very issue, but I'll quote them here, "Heck, maybe this is why there are so many Far Trader's floating around out there!"
Here's a handy table, presented in
