When you open a new board game, nothing makes sense because everything is new. The cards, the terms, the mechanics, and the characters.
You sit with the rule book for a while. You digest. You start piecing together what goes where, and who plays what, and how things work.
Eventually, things click. You get into a groove, you enjoy the game, and you start being competitive. You realise that the confusion and complexity at the beginning was necessary to grasp the depth and richness of the game.
True for board games, and for almost any other worthy pursuit.
