Normally, the NCR/House/Legion quest lines will force you to interact with these factions and gain their support (or prevent them from supporting your enemies) as part of storyline missions, but if you're playing the Yes Man/Wild Card track, there's a lot more freedom in who you deal with/kill/etc.


The point of the "Side Bets" quest is to get you to interact with (or ignore) these factions, who you might not run into unless you're prompted to do so. There are a number of factions in the Mojave that have the power to affect the outcome of the final stages of the game and/or the ending in some way.
