Yeah not being a silver tongued devil in Fallout 4... was basically asking for every single mission to fall apart.
The problem with FO4 is more that most of the quests just aren't any good (95% of all quests in FO4 are just variations on "go there, kill things, retrieve thingamajig") and that having high charisma, rather than being a testament of your character's quick wit and clever thinking was usually just "do a thing a normal person would do". The fact that instead of giving you interesting dialogue or story consequences it usually just saved you a quick firefight didn't help either.
It was much better in Far Harbor, but it was still hampered by the RNG nature of it and the monstrously crippled dialogue system.
I kinda wish more games would use a (modified, more robust) version of the Mass Effect stuff. If you're this big hero guy, people are going to take notice of what you're doing, so taking actions that fit with your reputation should be easier to do.
Threatening someone should be easier if you're known for bashing heads in when people don't agree with you, things like that.
I'm not sure how you get better at talking to people in combat-focused RPG's... Not specifically fallouts, either.
Old Fallouts kinda do that. You have a Karma meter and based on your karma, NPCs will react differently. Some things are impossible to do with high karma while others are only possible through having high karma.
It's just not really up front and centre as it is in Mass Effect.
Speaking of Mass Effect
Talking Someone Out Of Racism In The Span Of A Single ConversationJust no. I hate it when writers do this because it shows a complete lack of understanding for how racism (and humans in general) work. A deeply-rooted conviction isn't going to go away through a single conversation or a single well-constructed point. It can be a start on a long and bumpy road to change, but it's not instantaneous. Someone who's for their entire life believed that aliens are somehow less than fully sentient individuals with hopes, dreams, aspirations equal to any human's isn't going to drop those beliefs in the time span of a single conversation, regardless of how clever you think you're being with your BUT THEY FEEL TOO CAN'T YOU SEE bollocks. For deeply entrenched convictions to change, you need time and intensive work from both sides.
