Difficulty: Slow it down, don't dumb it down

Sitting down to play Super Smash Bros. for the first time is an overwhelming proposition for the average adult.  The game is a flurry of action, a camera moves in and out constantly, and the winner appears to be randomly chosen at first.  To top it all off, all characters start out at 0% (you're not told of what), a percentage that is increased every time they are hit.  Without instruction, most adults would give up on this game fairly quick, resigned to the fact that it's something they'll never get.

Grokking in three dimensions

Even if you accept that the notion of grokking and grok-tests play an important role in understanding games, you may doubt that winning is an indication of grokking in light of games such as foot races and lotteries where grokking the rules is clearly not the sole requirement for victory.

Grokking and Games

The term "grok" comes from Robert Heinlein's book Stranger in a Strange Land, and is a Martian term that roughly translates into "to drink," which also describes the Martian's take on the act or state of understanding fully--"to understand so thoroughly that the observer becomes a part of the observed."  If you haven't read the book yet, you probably should, as this idea of grokking alone is worth grokking.
