I understand the motto, easy to play hard to master. This really applies to PON. I have had the privilege to be in two games with very dedicated gamers. I continue to learn so much. When new players join to replace players who no longer can commit to the game, they are not uniformed novices, they have learned to master this game; and thankfully, they are willing to share what they have learned.
I just discovered, after more than a year of play, Britain's ability to build the units: Prospection Expedition and Exploration. I am eager to see what they can do in the field.
This game is so complex. If it weren't for players willing to share their ideas and knowledge about the game, I would still be in the dark instead of just in the ozone layer.
