Let's start with Benny, he recruited a small handful of Great Khans to come and get the chip with him as if he was going to be getting into a very dangerous circumstance with the courier in order to retrieve the chip. This doesn't seem like a raider tribe sacking a caravan, Benny knew something about you could be dangerous enough he would recruit some Great Khans to assist him in taking you down near Goodsprings. Fast forward to your arrival to the strip, if the Courier lacks the skill of diplomatic revolve ( speech ) or bargaining ( Barter ) with Benny your lead once more into a situation that Benny hopes will finally kill you. The Courier survives and Benny shakes town and decided to goto the Fort to use the Chip for himself, yes Benny goes to probably the most dangerous place in the entire Wasteland to infiltrate it to try and seize New Vegas for himself in what may actually be his third attempt to do away with you. The very idea that Benny went to Goodsprings with a group of Great Khans seems VERY excessive for a simple task, your virtually harmless armed only with a weapon of your chosen discipline that Doc Mitchell will hand over and virtually unarmored wearing clothing suited for a farm laborer This was not a stroke of bad luck, this was planned for you for a reason that may have nothing to do at all with the chip but the mere fact you are dangerous enough Benny wants protection and an excessive upper hand against you from the get go. That begs the question did Benny possibly know Ulysses would be the one holding the package and not knowing his face or his appearance assume you to be Ulysses as such you took the grave for him? If so what has Ulysses done that has him feared throughout the Mojave? Even if this case is wrong then what has the Courier done to warrant Benny to make such a play?
Next we have the NCR, you may not have any relation with them up until Boulder City that doesn't seem to mean a thing. First Chief Hanlon acknowledges you had been shot in Goodsprings and speaks with you as if your well known and yet you've done nothing for the NCR. Second, Ambassador Crocker sends for you personally despite you haven't put yourself forward in the local power game between NCR, The Kings or Caesar's Legion. Third, Lt. Monroe is willing to risk the lives of two of his men in your hands without any hesitation what so ever which is very suspicious. The Courier must once again have done something very important to have such early high recognition from the NCR.
Next Caesar's Legion. Caesar is willing to send one of his highest ranking men into enemy territory just to request meeting you in person despite your only dip in the power game was to make Benny as previously stated make ghost and head to the Fort. It's pretty obvious Caesar views all of the Mojave denizens as inferior to the human race and only worth enslaving. Now lets suppose you kill Inculta Vulpes in Nipton, he is still willing to send one of his top men to meet you despite you've proven just how dangerous your very existence is to the Legion. Couple this with the fact Caesar requests your audience your still recognized by the legion as a profilgate(sp?) that he is infact likely risking his very life letting you come within 2 feet of him putting his faith in four or six Praetorian guards to stop you if you really do opt to kill him means either his brain tumor is strongly affecting his judgement or once again surprise, surprise you have an unwritten and previously vast impact on the Mojave.
In conclusion Obsidian has only raised hype in the game for me because I have these questions I'd like to be answered and it seems so far as Bethesda has stated Ulysses is the only person who will open up to the character to explain just what has happened in his/her past. And from the sounds of things if these sorts of questions had been planned to be answered through gameplay expansions I'd have to say they've done well at attracting my money namely because there is two main story lines with one being unraveled a step further next Tuesday that sets the stage to answer all questions ( hopefully ) in September.
So, what do you think?
Edit: Sorry about the topic title, as I am writing this I am dead tired and these sort of ideas only come to be when I am tired. It won't let me fix the title, once again my apologies.
