I like to now, will the end quest always come, no matter ? i am level 30, i do quest every day, i wipe out all cesar legion, but still no sign for end of game,

will it be there automatic?

You'll have to progress in the main quest for the endgame to happen. As long as you don't accept the warning screen before the endgame, you can do whatever you want, for how long you want.

Ok Thanks, i must find what main quest are.

Think i find it in walkthrough.

there are different quest paths.

Render onto Caesar

For the Republic

The House Always wins

Wild Card-

if it has that in the name it is a main quest.

the other main quests that

when you get the quest to protect the president if you are on the side of the ncr, thats very close to the end battle.
