In my opinion, there are two sorts of moral choices in games. Those that influence the world and those that deal with the conscious. Bioshock is a conscious sort of game; the decision to harvest the Little Sisters or let them go does not affect the game world as much as it does in other games. Deux Ex would be a game that deals more with the world than the inward feelings.
The sad thing is, in my opinion, that the majority of games stick moral choices on their game like a shiny sticker to grab the attention of the public. Due to,as Yahtzee has often said, the public clamoring for "free choice" games, more and more games are throwing it in their to appeal to the mass market.
However, many games actually utilize decision making well and blend it into the gameplay, unlike games such as Fable, where your choices don't really impact the world as much as in other games.
