Everything is more focused on ncr, they even have a radio for backup but i have not seen anything like that for any other faction, ncr gets everything, obsiden imo [censored] over alot of options in the game.
Well, it's unfair to say they [censored] up the factions, when they are the ones who offered us faction interaction in the first place, Fallout 3 had almost no faction interaction, there were the good guys you had no choice but to help, and the bad guys who were hostile no matter what you did, at least Fallout New Vegas gives us the option of who to help and who to hurt, who to save, and who to burn.
