I had an idea just now, I thought that the ending of New Vegas did not portray my character well enough. So why not make my own? If you wish, you can write down who your character is and make an ending as though it were a slide in the official ending.

My first character is John Marshal, sided with the NCR and specialized in guns.
"Having secured the Mojave wasteland for the NCR, the Courier joined the elite rangers. And thus becoming the most feared opponent of the republic's enemies. Together with his companion Boone, they assured the continuing growth of the New California Republic. Later, he was even offered to lead the NCR's army as it's General. However, he declined this offer for he found it to be a position suited for a leader and not a warrior such as he. And for the rest of his life, he remained a hunter of dangerous prey and a wielder of dangerous armament."

My second character is Robert Neville, a science and energy weapons character who sided with House.
"After activating the Securitron army and taking New Vegas and Hoover Dam for House and he to rule, Robert Neville continued to be House's right hand man. He did disagree with House's rule however. He did not want anyone to be treated less for their intelligence, upbringing or any other factor of their lives. Under him, life was fair to all, equally. In the remainder of his years, he oversaw House's scientific endeavors, ever striving to unlock the secrets of the Universe."
