The author writes about balancing difficulty of DF. I've seen many people saying that DF is too easy once you figure it out. It's true that it isn't a difficult game, but I think it's missing the point. The point of DF is simulation, not being a difficult game. There's a lot of beauty in it. If you want to be challenged there are better games for that. If you want to explore virtual worlds or excercise creativity you've got a deal.
