According to Tweetdeck, one of the trending:worldwide topics on Twitter is 6 word stories.
I've asked for 6 words about game designers, 6 about programmers, and 6 about wargames, with interesting results. Now I want to ask about another type of game.
Can you say in 6 words what makes casual games interesting--or not? (And you'll have to decide what "casual games" are.)
