Makes sense. It's hard to enjoy playing a game when you're better than 99% of the people out there, but 90% of the other 1% can totally destroy you (random figures here, btw; just to demonstrate a mathematical point). That's how Scrabble has become for me, which is why it has lost it's interest for me. I can only enjoy playing against a very small amount of people who are actually at my level. If I take my scrabble board with me to a meeting with 100 randomly selected people, the chances of me finding someone who can play at my exact level is nearly non-existent.
It's a lot easier to lose to a strong opponent when you're not a serious gamer. It's a lot more daunting when you take games seriously, like ha~ma, KogaRyu, and I do. Realising that, in order to beat a certain opponent, you'll have to practice, study, and observe for years of your life, while that opponent is working just as hard to improve his or her own skills, is demoralizing to say the least. I still play Scrabble with my family, or with friends who I feel will be good sports if they lose by 150 points, or totally destroy me. But it's not something that I can try to play seriously because there's just so much learning I have not done.
Chess, in my opinion, does not have quite the same strategic depth. Certainly though, it exists under that same umbrella. A person must, as ha~ma has already said, live Go to become a master of the game.
I might drop by for a few casual games of Go, though I'm a bit foggy on the rules.
