When I went through the game, I didn’t even notice that Mr. House didn’t pay you for a majority of the work that you do. By that point in the game I had lots of chips and I just sort of assumed that each quest turn-in was putting some caps in my pocket.
I believe there are four endings to the game: House, Legion, NCR, and Wild Card. Within those endings, some of them have options, like what to do with the dam and Helios One.
Out of curiosity, which ending(s) did everyone go for? Did anyone do them all?
