Gambling in games

[Psychospacecow]

Basically, what do you think of it when a game throws in slots, roulette, blackjack, and craps like that? I personally don't mind the inclusion of things like this, but they're usually necessary to unlock certain things or complete quests/achievements, and frankly, that's a problem for me, because I'm gonna about to learn how to play a game to play a game in my game.
