Hello Jazzy, welcome to our forums!
You ask a great question. I think there are a few board games on the market designed specifically for EFL. If you are in Madrid, you ought to go to Booksellers in Plaza de Olavide (metro Bilbao) as they have a lot of that kind of material there.
I love board games and use them from time to time in my classes, but I just use normal board games. Monopoly is great for teaching financial expressions, numbers and requests/offers (modal verbs). Taboo is great for speaking skills and vocabulary development (you can play without the timer and without the taboo words to make it a bit easier), Scrabble and Boggle for vocabulary development/spelling, Guesstures for speaking skills/vocabulary development and also Clue for expressing opinions.
Hope that helps you in your quest
