The details make it harder to roleplay my own character of my own design. I feel like that's the miscommunication here. Myself and the people who agreed with my post are trying to create our own characters. Again, from my original post:
Even though Fallout 3 forced you to be a 19 year old and the son of scientist, the tutorial allowed you to determine what type of person you were, what your character’s interests were, what sort of occupation you wanted to have, whether or not you were a violent sociopath.
Nothing about your pre-set backstory determined anything significant about what type of person you had to be.
This allowed me to create a different character each time I played the game. In one playthrough, I was the star athlete of vault 101’s baseball team. My character used a baseball bat to bring justice to the wasteland. In another playthrough I was a mad scientist, an anarchic trouble-maker who, according to my aptitude test, was obsessed with explosives and science.
In Fallout 4, no matter what, I will be a middle-class U.S. soldier with a wife and child whom I apparently love.
OR
I'll be a middle-class lawyer married to a U.S. soldier with a child whom I apparently love.
Sure, I can randomly decide to go insane once I leave the vault, but I can do nothing to change the core aspects of who my character is.
Not only that, but the dialogue is very bland. You never really get a chance to flesh out your character’s personality. At best you can be sarcastic or hostile at times, but it all seems very disjointed and schizophrenic. The issue is made worse with the inclusion of voice-acting, so you can’t pretend your character is delivering his lines in a way that would make sense for the personality you chose for him.
So, I COULD randomly decide to go insane once I leave the vault, but whenever I decide to talk to someone, my character will remain calm and even-toned outside of specific situations.
So yes, previous Fallout games had pre-set backstories as well, and yes, it's POSSIBLE to roleplay if I just close my eyes and pretend, but Fallout 4 makes it much more difficult and gives me much more to work around than previous titles.
