For example, my kids rarely draw in Tic Tac Toe. At their skill level, it’s a very winnable game and therefore fun game and therefore viable game. But it’s not even a viable game for two adults who have studied it for a bit. All draws all the time.
Less expert players of chess also don’t draw often. The game is sufficiently complex where practiced adults still win and lose a lot.
But then you get to grand masters and draws become common. The game, as designed, seemingly becomes less “viable.”
But I’m curious if there’s a U-shaped game out there: viable for beginners, viable for experts, tedious for intermediates.
