Basically, the headline's the question.
It says the Life Modules System offers less Karma because some Modules are very good.
However, in case I just don't find a fitting one, can I just forgo that step?
F.Ex. the Nationalities offer only North and Middle America, and while my group plays there, having someone hail from somewhere else would be neat.
Then there's Corporate Born Citizens, which are left in the dust as well, to speak nothing of Cal Free (that should be there, you have to admit).
Aside, unless you specifically want to tell a story with your life modules, what's the point in White Collar over Corp Drone? Yes, a specializaton is 7 Karma, but I think 2 Levels in the Electronics group trumps that easily.
