I only thought it necessary to buy only one of the Narrator's Toolkits that came out for LUG Trek. In my youthful arrogance I thought that I wouldn't need that much advice on how to run a game in my favorite universe, and I thought it would suffice to have three Corebooks telling roughly the same, but not three NTs.
How wrong was I?!
I definately could need any help back in the day (and might still do) and now am curious as to what differences set the three guides apart.
I have - have I to tell - the TNG version of the toolkits.
