How many of the NPC's of the main factions do you kill before the last battle ?

When you do yes men or NCR/Legion how many of your enemy faction do you kill before the battle ?

When I do Yes Men I have to say I kill every single legion and NCR NPC I can find, killing ceaser and everything before the last battle.
How do you do it ? killing everything before it or what do you do ?

For my Independent run, I've been systematically eliminating the Legion throughout my playthrough so there aren't really any left by the time I get to Hoover Dam.

Nope you also can't kill Festus and unless you use TCL you can't kill the gunrunners vendatron
