Re: Greetings...
As I continue to design this game around GURPS rules, I have decided to add something other than just the Focus Skill.
When Character Points are issued, I will also issue "Codebreaker Points" (CDP). You will receive probably about half as many CDP as you do CP (although I'm still working out the balance).
Normally, in GURPS, advantages and the like are inborn and can't really develop. However, since the Matrix identity is a computer construct, these points will allow you to add certain "advantages" to your character, allowing for more diverse character improvement.
For example, regeneration or improvement on your Focus Skill will be possible through CDP, including numerous other "abilities."
I will also be introducing "Esoteric Skills," which in GURPS are cinematic martial arts types skills that fit seamlessly with the GURPS universe.
Any comments or suggestions as I continue to develop this? I am working on the list of Codebreaker Skills at the moment, mostly adapted from existing GURPS abilities.
