I have to admit, I have less enthusiasm for Fallout 4 now than I did when it was released. Part of this is me knowing what happened rather than going into the game excitedly, but that’s not everything. (After all, I loved New Vegas despite my runs adhering rigidly to walkthroughs)
I think one big thematic misstep, which one of my favorite game bloggers, Shamus Young agrees with, is making the protagonist voiced. It’s a sort of uncanny valley where they’re too detailed to just be a blank slate, but aren’t detailed enough to be an interesting character themselves.
(That I’m not impressed by the voice acting doesn’t help matters either)
I had three couriers for my New Vegas playthrough. One was a talker who sided with the NCR, one a brute who sided with Caesar’s Legion, and one a physically weak ex-gangster who sided with Mr. House to redeem themselves. (Said courier compensated for her physical weakness by getting power armor and blasting the final boss with a super-railgun).
Even games without the customization of New Vegas make blank slates. For the protagonist of Undertale, the players (eventually) know their name, that they’re nice, and that’s it. For a Pokemon trainer, their family is known, but they’re not.
I do invent backstories for blank slate characters that often contradict the rest of the setting. Why not?
