This is the first time I have games-mastered a campaign without being a participant and it is a lot of fun. I have been able to keep each side in the dark before each game especially the marines. This is only reasonable as the Japanese have occupied the island for some time so have local knowledge. Accordingly the IJA have seen all the terrain maps at the start of the campaign but the marines only get to see them just before each game but I can send them intelligence to give them a chance to prepare.
