Heh, Alien Power Cells

And about Poker: Have no fear, PC players! Some crafty supermodder will surely implement poker, thanks to Obsidian's Blackjack and other games base!
I hate to be negative, but the AI and gameplay mechanics for Poker, especially popular variations like Texas Hold'em, are quite a bit more complicated than Blackjack. Remember, in blackjack you are only playing against one opponent - the dealer, and the optimal strategies for the game are pretty simple. Vegas rules state that the house dealer must stand on a hard 17. Depending on how many decks of cards Obsidian has programmed the blackjack game to use, card counting may even be possible.
Poker relies more on luck, a knowledge of possible hands, and bluffing and anticipating the possible hands of other players. This isn't something that can just be tacked on top of a Blackjack code base. No, I fear if Obsidian has not added Poker to New Vegas themselves, we are unlikely to ever see it.
