I love playing these kinds of games, but I don't think that they map very closely onto real world situations, If I'm deciding in say Fallout 3, whether or not to detonate the nuke at the centre of a town or diffuse it, I generally select detonate because I know that I'm in a game world that doesn't feasibly map onto my real life at all, I'll likely never have a chance to see what happens when I would inflict this kind of chaos, nor would I want to if there were real consequences. But in the videogame world, I simple cackle away at the chaos and see what happens from there! There's also been some really interesting research done on how videogames influence our co-operation and feedback mechanisms by modeling the fact that choices have consequence in real life and that they may actually be a great place to practice making choices without real consequences that set people up to be more decisive in real like. This is paraphrasing some things said by Jane McGonigal, authour of a book called "Superbetter"
