MegaTraveller is an awkward goof in the history of Traveller. On paper, the idea of a fresh new edition of the game which gathered together the cream of the crop from various disparate supplements and accessories in order to provide a brand new unified version of the rules – complete with, at last, a universal task resolution system, something vanilla Traveller had been sorely lacking – was a good one.
Unfortunately, slightly too much of MegaTraveller involved just slopping on the advanced options from Classic Traveller without much consideration as to how likely it was any particular group wanted all these dials turned up to 11 at once. Moreover, the core books are absolutely riddled with errata; the Consolidated MegaTraveller Errata is some 71 pages long, and of those pages 4 consist of explanatory material at the start, 48 consist of errata for the MegaTraveller core books, and the remaining 19 pages cover errata for some 11 supplemental products – coming to less than 2 pages per supplement on average, whilst the MegaTraveller core set has an average of 16 pages of errata per book therein.
Now, it’s true that some of this errata consists of clarifications and additions rather than actual errors – and a few of the corrections already made their way into later printing of the materials. Still, it’s clear that the task of actually implementing all of this errata to the entirety of MegaTraveller, even if you limited yourself to just the core books, would be a mammoth undertaking and, arguably, not really worth the effort – especially when the Classic Traveller material that MegaTraveller was based on (or the Mongoose Traveller stuff that came out later) is more accessible and much more amenable to letting you pick and choose what to use.
That said, what scope is there for using MegaTraveller not as a rules set in itself, but as a body of work to draw on for other Traveller games, particularly Classic Traveller or other systems closely related to it? I decided that was a question interesting enough to merit further investigation, particularly since some of the MegaTraveller materials out there is substantially cheaper to find hard copies of than the Classic Traveller material it draws on.
