I rather liked the Lord of the Rings Living Card GAme from Fantasy Flight. The designers set themselves a really hard task, to design a card game that would give the feel of Middle EArth. I think that in general they did a fairly good job, but one major gripe I had with the game was the excursions they took from phrases in the text to create game mechanics they needed.
I think that a few of these textcursions have crept into ToR. The one I'm thinking of right now is the tiny fairies west of the Shire from the starter set, extrapolated from the notion that some hobbits took a fairy wife, as quoted from The Hobbit.
Given Tolkien's known disdain for Victorian tiny fairies, (I think he called out J. M. Barry specifically somewhere) this feels like an unfortunate, overly literal reading of this throw-away line. Whether one reads the Hobbit as part of the legendarium, or as a separate story, as it was originally, before JRRT ret-coned it into the larger context, "fairy wife" always felt to me like hobbit myth, rather than literal fairies, especially diminutive ones.
Let me hasten to add that this is not a deal-breaker, though it was a record scratch moment for me when I read it.
