I think my best character was named Jason Cage, a boy who had a bad relationship with his father until his father left the Vault. He left and wandered the norhtern regions of the wasteland, trying to figure out what to do with his life until he went to Megaton and defused the bomb. Then he saw Nova, who he had hired three or four times, jump from the balcony of Moriarty's Saloon (I had thought it was a scipted suicide but later found out it was a glitch). Jason fled into the wasteland, butchering raiders, slavers, and supermutants until he found Underworld. He helped out all he could for the ghoul settlement until he meets Mr. Crowley. He helps him by killing Ted Strayer and Dukov before figuring out his true intentions. He then decides to get the armor Mr. Crowley desired for himself, killing Mr. Crowley and Allstair Tenpenny. He managed to find Dave at the Republic of Dave but left when he saw Dave's children, feeling even more lost. He went back to Megaton after a month of travels and helped out a bit. He helped Lucy West by finding her brother and Leo Stahl get off of drugs. Then he decided one day, while listening to Galaxy News Radio, to go visit Three Dog and help him any way he could. He went there and got the Washington Monument a replacement dish before he tells Jason Cage that his father went to Rivet City. He was overjoyed and rushed sown to Rivet City to find Dr. Lee and that his father went to Project Purity, then he finds that he went to Vault 112. After freeing his father from Tranquility Lane, his father dying at Project Purity, and being told to get the GECK he went back to Rivet City and found out about the Temple of the Union. He went there and helped them by moving them to the Lincoln Memorial. After that he retrieved the GECK and was captured by the Enclave, being saved by Fawkes the supermutant. He then found Bigtown and helped them in any way he could. After a long time at exploring he met Tobar the Ferryman and went to Point Lookout, aprenticing himself to Desmond Lockheart and fighting the horribly mutated hillfolk. Eventually he helped Desmond, with his dogs Freki and Geri, had their final confrination with Professor Calvert. After Desmond's victory Jason went back to the Capital Wasteland to help the Brotherhood of Steel with their final push against the Enclave.
I said there'd probably be spoilers.
