Tradition is no reason to stick with something
I agree. But, if you must have tradition, it is better that it be say, the beginning of a video game, or a holiday where you get to wear whatever you want and strangers have to give you candy, rather than any other tradition that dictates what you wear, eat, who you marry, etc etc etc.
In game origin story? No. But they need to find a way to incorporate stronger RPG elements without being restrictive, which is easier than it sounds.
Okay. Let's say your character is was a noble Knight. You are in prison because you were...framed, punished by an evil person of greater rank, guilty of a crime which had a noble cause.
You shouldn't need the opportunity to play as a noble Knight before you are thrown in prison, because that would be either super complicated, or incredibly linear for the infinite number of character types you can make. Even a company like Bethesda would have to favor linear, Dragon Age is supposedly a trilogy, so the origin itself is a full game, which would be pointless boring plagiarism for Bethesda to emulate.
Instead, the skill that you choose for your character will dictate hoe you play when you are out of prison, and therefore what you were probably like before prison. There should not be too much wiggle room, but there should be some growth. I actually just thought of a new system now, which I will put in the suggestion forum.
