Interesting, I liked the Kefling game that was given as a game with gold some time ago. "Kingdom of Kefling" I think it was. But I'm not sure I'd buy one. It's a great way to pass the time, watching your little guys moving resources around (reminded me of the old Settlers I was playing as a kid), but it's not exactly exciting.
*e - wait, they didn't even spell Kefling right in their hashtag !
