Good evening folks

I have just fairly recently taken up the position of Captain Nemo in the game and I am really trying to get my head around the game mechanics. I previously had a character in Scramble for Empire, very much like the Swashbuckler game, but he lapsed a few years back. Now that I have taken up the Nemo position, i am trying to play it in a character driven type of way, which is great fun, but doesn't really reflect the rulebook type of play. I have few assets to play with apart from one submarine and a few characters to command. Has anyone previously played this position, or one like it that could give me some advice please. I have previously played Portugal in GOKs and had single characters in both Swashbuckler and SFE.
Many thanks for taking the time to read this, and for any advice you may have to share.
