I don't like the BoS, the Institute or the terrorists of the Railroad. BTW I also don't like the Minutemen but that's more because of the tedious settlement stuff and Preston's talk that's so sweet and slimy that I get caries from it.
Do I need a certain number of settlements/artillery/minutemen as help to destroy the three other factions? I don't intent to have more than two settlements at all that I support (and that's 100% more than in my first play session).
Once I wandered the world at low level and a mean looking Deathclaw appeared near me. Luckily at the same moment three BoS PA-guys on patrol with gatling lasers rounded the corner and made short work of the monster. I'm a bit afraid to battle against these guys alone. Will the minutemen be of any help?
