Seriously this opens up so much creativity for the DM.
“This person seems familiar to you, but you’re not sure why.”
“You think you’ve been here before, but you’re not sure when.”
“Being on a ship feels like home, but you have no memories of ever being on a ship.”
“Upon seeing the ruins of the village you find yourself overcome with sorrow, you feel like you’ve lost something important but you don’t know what.”
Part of the adventure can be a quest to reunite them with their lost memories.
You forgot how to piss, shit, bathe, heal, feed and dress yourself when you gave up your memories. In fact, you forgot how to walk.
This is pretty much what’s happened with my latest character.
I’m playing a reborn/dragonborn, who had previously tried to fight Strahd but lost. And a part of that loss means that my character lost a good chunk of his memories of fighting Strahd before.
But Strahd still remembers my character. So it has lead to some interesting interactions.
I actually agree, that could be pretty fun. That said this puts a lot of work / pressure on the DM so it is definitely something to be discussed rather than used to be lazy. (To be clear, I am not reading this into what you said. Just saying it out loud is all)
I’m a forever DM so I’ve got so many unused character ideas that turn into either NPCs or if a player is like “I forgot to make a backstory”
But with the amount of improv I do as a DM it’s very little effort for me.
Though I agree it should be discussed as part of session 0. As it’d be rude not to.
Session 0 for my groups is always the same really, we sit around boucing ideas off of each other for characters, things we don’t want to be touched on during the campaign, and what kind of campaign we want.
Look, if I wanted to write 100% of your backstory for you, I’d have been a player. Ttrpgs are meant to be collaborative. I already have a shit ton to do as GM, you could at least throw me a bone. Even if you want to do an amnesia plot, that doesn’t mean you the player doesn’t know anything at all.
Yuuuup.
Fiend warlock player did not like learning how I used his minor backstory. (He actually loved it.)
He knew he needed to save a tree. He didn’t know he was the one to burn it, nor that he did so because it was a source of power to his mother, who was a night hag.
So much fun.
He saved the tree and even managed to change his Patron, but is too scared to confront his mother again.
I walk up to the bartender and ask him about rumors.
Bartender: “You son of a bitch, I told you if you ever come back, you better be able to pay your tab!”
DM: “Alright. Everyone else, please make up and write down two things about this player’s backstory and let me know. Do not tell each other what you wrote. I’ll choose which ones I’ll use plus may throw in a couple myself” evil laugh
