I'll just say that my character will be for a better future, but will also be an "end justify the means" type of character if push comes to shove.
Also, it won't be a main goal to make the wasteland a better place. Survival will be the prime concern. So I'm sure she'll end up doing some good things but she won't be a "do-gooder" per say.
I'll play on Normal and with hardcoe mode.
I'm gonna try a different build and specialize in Speech, Science and Barter. It'll be an intelligent and fairly charismatic character, and fairly weak otherwise.
