The solution to the problem is complex with many intricacies, but the main focus of the problem for many people, I think, is that their character has no story.
This will go on with people making new characters and never getting attached to one.
Yet, they will get bored of it after a session or two and want to kill off their special character to make a new one. I have often seen people make characters that seem really cool and badass and have plenty of backstory and are incomparably unique. How do I make a character that I won’t get bored with? I have seen the problem take place all the time with no one really knowing what the problem is and whether or how to fix it. So I saw someone ask a question that I myself have asked before.
