It's got the basics covered, and it's got a good variety of weapons, but I could still really go for a big book full of stuff, notably in the non-weapon category.
More weapons; More utility equipment; More toxins and poisons; Drugs of various types; Weaponized (and non-weaponized) pathogens; More vehicles; More Cyberware; More Armor; etc. A bunch of my players expressed that there didn't seem to be as many options as they had hoped for, and I can see what they mean.
I know there's a little bit of fan-equipment. There's that big thread of ships. That will help when they are in the market for ships. I think I could go for conversions of the other equipment from SWd20/SWd6 as well. For my own game (since it's not a starwars game, but more of a homebrew mashup scifi game), I'm leaning toward starting to convert equipment from Shadowrun 4e/5e.
