I'm discovering different aspects as I play more. There are faction missions, which get you reputation rewards depending on which ones you choose. But as for the regular missions, it's a simple yes/no for completion if you hit the last target number. There are 4-5 steps that each require a certain score in a main skill (each step has 1-3 paths). Each character has a rating on 1-3 skills (the less you have the higher your score). For instance:
My "Captain Kirk" has 61 Command, 48 Diplomacy, and 24 Security. In addition, there is a spread of final skill values that are used when he attempts a step. This Kirk has (6-16) for Command, so his base of 61 will have at least 6 added to it (for a minimum 67), or 16 at maximum (77 being his highest possible score).
There are several skills (think 1E classifications). Here are the ones I've seen:
Command
Diplomacy
Engineering
Medical
Science
Security
Along with this, each character has 2-8 traits (this is what we might think of as keywords or skills in the CCG world). Here's a smattering:
Android
Astrophysicist
Augment
Bajoran
Betazoid
Brutal
Cardassian
Civilian
Costumed
Counselor
Cyberneticist
Desperate
Doctor
Duelist
Empath
Exobiology
Explorer
Federation
Ferengi
Gambler
Geneticist
Hirogen
Human
Hunter
Innovator
Inspiring
Jury Rigger
Kazon
Klingon
Maquis
Maverick
Nurse
Pilot
Prodigy
Resourceful
Romulan
Saboteur
Scoundrel
Senator
Spy
Starfleet
Survivalist
Tactician
Tailor
Telepath
Thief
Trill
Undercover Operative
Vulcan
Writer
Each mission has traits associated with it; if you bring personnel with those traits, they may give you bonuses on related checks (i.e. a Diplomacy check might get a bonus from Empath or Telepath).
It's a neat simplification of the general mechanics of 1E/2E missions, with a little bit of luck thrown in.
