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
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.
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.
I once had a player in my game play a changeling who swapped places with someone, then forgot they were a changeling. So naturally, I had the rest of the party meet the original without her. That was a fun reveal.
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.
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.
In other words, "My backstory is whatever you want it to be".
If you were the DM and this bothered you, the player just gave you powerful ammunition.
You could even have it so whenever the player entered a shop in his home town, the shopkeepers looked at him with disgust and refused to serve him. The DM wouldn't even have to necessarily come up with a reason. Just, that the player is extremely well known among the locals and they universally think he's absolutely disgusting and want nothing to do with him.
Yeah, i find this to be awesome, because i can now leverage the other player's back stories into WHY they lost their memory. Or use it as an inflection point to shove the players a bit.
Gonna be honest, I usually make my backstory like 2 or 3 sessions in, that way I get a feel for the character and can do something that makes sense. I usually start off with a rough idea, but I like incorporating themes from the story into my background
As long the player is open to whatever the DM decides their characters history is, or they have collaborated on an outline or even a detailed history the other players just don't know about, that is all fine and can be really fun for everyone.
If they are doing it with no heads up and are not going to play along with whatever the DM decides happened in their past, then no. But when it comes to DnD, I normally let stuff play out and only stop play if something is clearly going poorly, or might make other players more uncomfortable than they are willing to be. I only play with friends, so things rarely end up being anything close to the worst they theoretically could have gone, socially.
There was one where he said (in character) that a lot of people in the comment section write "barley" an inconvenience but I can't remember which one it was. I thought it might've been the 100 or 200 episode specials but no dice.
I never create a backstory. All my characters had personalities, different ways of solving problems, and I acted out the characters in their own unique ways.
All my characters are built around an idea. Ideas like "Kobold snake oil salesman", "Necromancer Child Edutainer", "Skaven Engineer", "Communist Dwarf", "A delusional ghoul named Jeff Bezos", etc.
Since, I do a lot of improvisation, not having a back story allows me to adapt my character to the story.
If that's the card they want to play then it's only going to hurt them until they start giving me something i can run with.
As a general rule, im willing to match and even exceed the effort players put into their PCs, provided they have done anything more than a statblock with a name.
But if they just have the statblock and name then I'm not going out of my way to customize content and quests specific for them.
If I were DM, congrats! You're hidden backstory is that you were one of the most depraved rodeo clowns to ever have existed. You were patient zero of a necromantic crotch-rot epidemic plaguing your birth-nation to this very day. You traded your memories for the cure. No one recognizes you because you're not wearing your signature make-up and are wearing more than just chaps and a crazed grin.
