Fallout: New Vegas Quests

=Story Quests=

Linear Quests
These quests are NOT optional and must 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
For these quests you must choose only one faction to be loyal to. The quests for the other factions are failed when you gain infamy for siding against them with whichever faction you choose. The choice between Mr. House and Independence/Yes Man is made first during Wild Card: Change in Management and The House Always Wins, but the player is still able to choose between this choice, Caesar's Legion, or the NCR for a little longer. The final choice on a single faction must be made after the player floats up the B-29 from the lake for the Boomers (or immediately after the first choice if you have already completed Volare! previously). After completing the quest Volare!, the next step is to report to Caesar's Legion, the NCR, or Mr. House/Yes Man that the boomers will assist them in the fight at Hoover Dam. Which faction the player reports the Boomers support to locks the player to that faction for the remainder of the game.

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. There are also achievements/trophies for two of the final quests for each faction so getting all achievements would require four playthroughs of the final missions.
