Which quests should I take to get an independent New Vegas and happy endings?

Solution 1:

"Good ending" is a matter of opinion, particularly when dealing with complex and occasionally irreconcilable factions of New Vegas and especially when considering the independent ending. Personally I think House or NCR are better for Vegas.

If you roleplay as a good character and do the quests in a good way, you'll usually get an ending you like.

I'm only going to cover the quests that are required, that always appear as an ending slide, or you've specifically mentioned. If you can ignore something without it appearing as an end slide, I won't mention it. A full list of endings can be found here.

Here's your to do list:

• Use the platinum chip to upgrade the securitrons
• Repair Rhonda at Black Mountain (you can instead kill Tabitha- either is better than just freeing Raul)
• Complete Raul's quest, Old School Ghoul. Pick whichever choice you prefer.
• Don't destroy the Brotherhood of Steel bunker
• Kill all the fiend leaders. Sucks to be them but they're raiders.
• Do not stop Lily taking her medication
• Ease tensions between the NCR and Kings by completing GI Blues and Kings Gambit diplomatically
• Get Rex a new brain
• Complete Flags of our Foul Ups by training the Misfits
• Complete Come Fly With me by helping Jason Bright
• Convince Boone to make amends over Bitter Springs
• Deal with the Powder Gangers in Vault 19
