Fallout: New Vegas Quests

=Story Quests=

Linear Quests

 * These quests are not optional and must all be completed in this order, regardless of faction affiliations.


 * Ain't That a Kick in the Head
 * Back in the Saddle
 * They Went That-a-Way
 * Ring-A-Ding-Ding

Game End Quests
Independent/Yes Man Quests:
 * For these quests you must choose one only one faction to be loyal to, but the choice isn't forced until the second quest for Yes Man or the NCR, allowing the player to potentially begin the final quest line for three of the four factions. The quests for the other factions are failed when you gain infamy for siding against them with whichever faction you choose.
 * Whichever faction you choose, completion of the final quest initiates a end cut scene after which the player must load a save to continue playing. I would recommend keeping a save from before you choose a faction to be loyal to and loading all the way back to that point, because after a faction is chosen, all the others (excluding Yes Man) will become hostile to the player.  So in order to complete all of the side quests available in one game, it would be necessary to load to a point three to four quests back, before an affiliation is chosen.
 * Right after turning in the platinum chip at the Lucky 38, either to Mr. House or Yes Man, the player should receive a message from Caesar about your past crimes to Caesar's Legion being forgiven and asking the player to come to the Legion base to meet. After receiving this message is probably the best time to save a file for returning to after completing the game.  The player should still be fairly neutral to most factions and at this point it is still possible to complete most side quests or to choose any of the four final quest lines.
