The games in the Fallout franchise are the only ones I preorder sight unseen. This has led to some occasional disappointments, but the Fallout universe is one I've immersed myself in every few years for about two decades now. I once cosplayed as a Vault Dweller (mashed up with a Stormtrooper) and walked through central London, surrounded by similarly eccentric folk.
Some of the appeal of the Fallout games is that they're ripe with dark humour. You may be wandering the post-apocalyptic wasteland, littered with irradiated skeletons only to stumble across a circle of garden gnomes apparently worshipping a bulls skull. Perhaps you turn a corner to find a teddy bear casually placed on the rim of a toilet, holding a newspaper, with a pair of reading glasses balanced neatly on its head. The scenes themselves are odd, self contained stories that are meant to make the world seem a little off-kilter. Maybe some lunatic is roaming the area, amusing themselves with these little dioramas, but the part that makes me chuckle is that lunatic is actually one of the game developers.
Perhaps the most disconcerting moment I've had in a Fallout game is with the recently released Fallout 76. While making my character, I heard a conversation between two people about a disreputable partner. Initially I thought the conversation was vocal lines from the game, but when they said the phrase “Hang on. I'm just making my character in Fallout 76.” I realised that I was listening to a player talking on their phone. The conversation took a very absurd turn, with some incredibly colourful language, and it was at that point I checked the options menu and found there was no push-to-talk feature in the game, and that all audio picked up by players microphones would be broadcast for anyone nearby to hear (whether they wanted it to or not). What an terrifying design choice.
As an aside, listening to that conversation between two unhappy people has really expanded my vernacular; unfortunately I'll never be repeating those phrases in public.
