no matter how much i try i cannot find a good ending it always ends for me where some people suffe, e.g. goodsprings is basicly abandoned becuase of NCR tax, or mr house killes the kings for helping the NCR ect...

is there any way to get the best possible out come?

Hi,
I was asking myself the same thing.
My NCR ending was okay but not ideal.
Best part was NCR and BoS fighting along with me, together.
But I really liked my YesMan ending - I talked the Legate into leaving, then had General Ncr thrown off the top of the sniper tower and into the dam!
That was a great ending (probably my favorite so far).
But the slideshows are mostly 'in the books' already before you even hit The Strip, y'know?
Regards

Yes Man is the best endings.

The game isn't about black and white good and evil choices, it's about making moral ambiguity. I think the 'best' call is Mr. House, personally.
