After picking up my first two FFG supplements this weekend, I've been thinking about what I'd like to see form them in the future.
I grabbed Suns of Fortune, which I'm just starting to thumb through as I type this, as well as Dangerous Covenants, which I checked out fairly thoroughly over the past two days.
I like the idea of books to flesh out each of the careers, and can't wait to see what they offer for some of the other ones, but I'd also like to see kind of an FFG equivalent of the RCR Heroes' Guide, with a host of non-tree talents, alternate uses for skills, extended talent trees, etc.
I'd also like to see a "kit" book that focuses entirely on weapons and gear.
I also really like the direction they're going with Suns, focusing on a specific sector rather than an entire region of space a la Coruscant and the Core Worlds. While those books are fantastic as sort of an encyclopedia, and I really like the ones I own, you can't help but want more in-depth info. I'm hoping Suns will offer that, and that they perhaps go on to focus on other sectors, or small groups of worlds. I think that a hardback supplement titled Glorious Jewel, covering Nal Hutta, Nar Shaddaa, and the rest of Hutt Space (Klatooine, Ylesia, etc.) would be a fantastic addition to the EotE lineup, and I think it's been long enough since the WEG days for them to take a crack at the Corporate Sector themselves.
Finally, I think that it'll be a necessity for them to do some sort of alien species compendium as well.
