While there is tons and tons of information about this setting, and it is organized fairly well once you know what you're looking for, it is rather inaccessible for a new player. There really needs to be a page that just paints the universe in broad strokes and explains the general story. Hopefully with a small section at the bottom that tells you the current state of affairs. As few technical, in-universe terms and links as possible on this page, so you don't wander off trying to figure out what a certain term means.
I was stuck on the New Player Guide for a while, as I randomly discovered page after page of info in the wiki. I was so overloaded with information that I didn't notice the link to the actual character creation page, which is a bit more helpful, until much later. You might strip the New Player Guide page of most of the links to anything but the creation page, to funnel new people there more smoothly.
The plot page seems like it will be helpful to people who are already established in the game, who want to check up on other groups. To me, it's just a jumble of random names and numbers. Clicking on a ship gives you more info, but most of it is still too specific and actually has too much information. Most of them start out describing the ship itself, the crew and lots of technical jargon related to its creation and assignment. Great for people who know what that means, but it's just another jumble to me.
The plots associating with a ship is a good way to handle it. But, either the main list of plots needs to have a summary on that page for each plot, or the main page of the plot should ONLY be about the plot. With a link to the actual ship and crew inside of the plot. It's more important to me to have a general idea of what is going on with that plot/ship than to know the ship's registration number.
But, in general, the information overload is the biggest problem. I was so interested in small details that I wound up missing the big picture.
