The Brotherhood of Steel
at least the brotherhood of steel has good intentions, (although selfish) while the enclave wishes to rule the wasteland for themselves, and cause chaos
They aren't the worst thing in the wasteland at least they have good intentions much better then the enclave intention to cause chaos and rule with and iron fist.
How could you choose the Enclave after they made your Dad commit suicide in Fallout 3.
I'm so excited for fallout 4, I hope the enclave is in and they play he good guys.
in fallout new Vegas the brotherhood of steel wants to out last every one so they hid in a cave and protect their tech in fallout 3 the enclave wants to make everything the way it was as the brotherhood of steel just wants to not face the destruction of super mutants and would rather go to war with the enclave
