I just rolled back someone's edit to add scrabble. I really don't think we need tags for things like Scrabble, Boggle, etc. Perhaps we can just use the more generic word-games? Also, is there a meaningful difference between games and word-games?
We don't need those tags because EL&U is not a site about board games.
Tags help to categorize the questions, but the categorization level must not be too detailed. Thus, tags such as fruit-nouns, pet-names, tree-nouns are not necessary because EL&U is not supposed to answer in detail to questions about, e.g, fruit nouns; there is already nouns and that is enough for the purposes of the site.
As a side note, I would add that such tags would make users misunderstand the purpose of the site, and I feel them more dangerous than the questions about jokes.
