I read (in issue 4 of MegaTraveller Journal if I recall it correctly) that there were three versions of MT. The last one were supposed to have all previous errata fixed. I have two sets of MT. One is in pristine shape, never played, and is riddled with errors. The other copy (very well used, almost falling to pieces) must obviously be a later version as most of the mistakes are corrected. But there are no clues as to which print run or version they are. So, when buying old games, for example on ebay, you never know what you'll get.
As for TNE there were actually errata corrected versions of the main rulebook, FF&S and Brilliant Lances. They are marked with: Mark 1, Mod 1 on the title page in the beginning of the book.
Can anyone confirm that this is true?
I can't wait to get home to check my copy. "Mark 1, Mod 1"
It is a pristine edition, so I won't get my hopes up....
