You know when you ussually start a Fallout Game?
It'd be really cool if there were some Vaults,
And you could choose what Vault you'd want your main story to be at,
Like,
You choose what Vault you are born in,
And do a main Quest for it...

You may be looking for the section above the fan fiction.

There is a thread for ideas about the next Fallout game here -
