That's not entirely true. The basic rules are easy enough for a kid to learn, and to enjoy playing against other kids. It's only when you start getting better yourself, as you start learning more and more, when you begin to notice it gets gradually tougher and tougher. But when playing against someone your own strength, you will always pretty much know what you are doing.

It's only when your opponent is a lot stronger when you will start to think the game is infinitely more difficult. ;)
