I love how Bethesda gives you the option to end the game in different ways. Especially because each ending has its different consequence. I did the Mr. House ending in my first play, but I was unsatisfied with it. I thought the it would turn up into a good ending, but that wasn't what I got. So I would like to know what is the best ending that one could get. I know it depends on several points of view, but thinking on the people of New Vegas, what is the best ending for the people? I would be glad to receive some answers.
Obsidian made New Vegas, not Bethesda. But yes, the endings were superbly done.
If you want the best ending for Vegas, go with House. If you want the best ending for the common folk in the Mojave, Indie or NCR depending on what you think of as good.
