I think Lock Pick should only include purely mechanical locks. We could probably just turn the hack skill into tech and change Lock Pick to security, actually. Also, I'm thinking we should consolidate PSI attack and defense into simple PSI. For other skills, I'm thinking we add Marksmanship for ranged weapon specialy and HtH for melee combat specialty. I think we should also add "Conversation" to serve as a persuasion/diplomacy/manipulation kinda check. And a Stealth skill would probably be useful, too. I'm less sure if we need something along the lines of "acrobatics," or "mechanics,"
Also, i guess I'll keep trying to flesh out the PSI abilities, just to get something more substantial than what we have now.
