freemind: You are correct on all counts my friend. You were somewhat "preaching to the choir" though.
If you check my profile my word usage chart says I average close to 53% ultra rare words. I see words I've never seen in my life every day when I play (quannets was the latest). I'm one of those people you described. I play between 50-70 games a day since I'm disabled. It takes my mind off my chronic pain and I never get tired of it. It definitely is addictive, been doing it every day for 3 years now.
Kind regards and happy gaming
