I think I’m able to explain things because understanding wasn’t entirely easy for me. Some things that the most brilliant students were able to see instantly I had to work to understand. I can remember what I had to do to figure it out. The very brilliant ones figure it out so fast they never see the mechanics of understanding.
The biggest problem you face when introducing a new abstract game, is how to make a player aware of the difference between a good move and a bad move. Most will get the impression of wasting time if they don’t start having a clue about what to do after, let’s say, two games. If the click hasn’t come by then, most will never start a third game.
I think that many will agree that abstract games are the purest of all games: a board, pieces and a minimum of rules; no story, no dice, no money, nothing but sheer essence; all information is there, thus so are all the answers on all possible questions.
