General information
Quests that are underlined reward an Achievement/Trophy. For each faction/location, quests are first in chronological order, then in alphabetical order if there is no chronological order.

Main quests
For the rest of the main story 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 an independent New Vegas is made first during Wild Card: Change in Management and The House Always Wins, but the player is still able to choose between 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.

Whichever faction you choose, completion of the final quest initiates an end cut scene after which the player must load a save to continue playing. Keeping a save from before you choose a faction to be loyal to is recommended. 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.

Wild Card (Yes Man)

The House Always Wins
A New Vegas ruled by Mr. House.

An New Vegas ruled by the New California Republic.

Caesar's Legion

Boomers
Volare! is the first quest you'll receive upon entering Nellis, and the last quest you'll complete for the Boomers. You aren't required to complete all the other quests, only as many as it takes to get the Boomers to idolize you.

Brotherhood of Steel
Still in the Dark is the first quest you'll receive in the Hidden Valley Bunker. Depending on who you side with (McNamara or Hardin), only their corresponding quest will be available (Eyesight to the Blind or Tend to Your Business).

Unmarked quests
Aside from the major quests listed above, there are a number of minor ones that are not listed as quests in your Pip-Boy. They don't count as achievements or trophies either.

Repeatable quests
Some characters want specific items. These can be repeatedly given for xp, caps or Karma.
