Scrabble Players?! OMG!!
I'm not really too sure what to make of 'Exactly the sort of people you imagine when you think "Scrabble player" ', other than to conclude that our author Kieran doesn't play, and possibly has a low opinion of those who do. Personally, I imagine simply someone who enjoys engaging their brain for the pleasure of it.
Scrabble has already been significantly degraded in recent years by the addition of numerous words using 'Q' to supposed english dictionaries that happen to be much easier to play in scrabble than older 'Q' words. Q being a high scoring letter, that increases the importance of luck over skill.
"Collins Official SCRABBLE™ Words dictionary" might seem like a useful addition, it does have the advantage of being definitive, but it raises the temptation for those selling it and the game to add new words just to push sales of new editions of the "Dictionary".
Myself and other players I know generally find the greatest pleasure in not letting the competition eclipse other aspects like keeping the pattern open and extending, rather than shut down just to grub out an extra point or two on a given play.
I actually find something allegorical in that, but perhaps that's exactly the sort of BS one would expect from a Scrabble Player. . . .
