Xbox – ny way to get the Faderator in Fallout: New Vegas on the 360

Luck: I haven't found any official confirmation of exactly what the percentages are for the influence of Luck, but I've the standard advice for high (9 or 10) Luck builds at Blackjack is to basically always hit at 18 or below, always stand on a 19 or 20, Split 16's and double down on 11's, and you will always come out very far ahead. Based on anecdotal information, it seems as though the impact of luck may be at least somewhat exponential, as I can't say I've had that level of success running with 5, 6, or 7 (the highest I've taken a character to the tables with.)

Deck: It's a shoe at Gomorrah at the very least, though I can't say how many decks, reshuffled for every hand. The main thing to keep in mind is that the odds of a 10 are extremely high when it's just you and the dealer.

Push: You're imagining things. In the event of a Push, you'll get your bet back, but you won't win any additional caps. That said, each Casino does have it's own house rules. At Gomorrah, the Dealer is required to hit on a soft 17. At Ultra-Luxe and The Tops, the dealer will always stand on a 17.

You could maybe argue that the Followers of the Apocalypse are "Good Guys", but even they refuse to offer assistance to the Strip without some coercion.

As far as the four primary plot paths go though, no, there's no black and white to be had. All four players have redeeming qualities, and they've all done (varying amounts of) extremely questionable, if not outright irredeemable stuff.

In general, the moral choices in FO:NV are not about good or evil. They're about priorities and willingness to pay various prices - which makes for a much more interesting moral landscape.
