I like the way you think.
I completed the quest and got rid of Nero and Sal. So far I let Cachino live, but the game's not over yet. There's still some loose ends.
A lot of people, including Mojave residents, see Gommorah as a Glamerous place to over indulge in six, booze, and drugs. But when you pull the curtain and dig deeper, it gets ugly fast....and that's when you go in with mini-gun to clean house.
One of the few things I don't like about House is that he supports putting such sleeze bags with enormous power and wealth and gets mad at you if you wipe them out. House's libertarian attitude and profit-motive doesn't justify what the Omertas do.
