My own choice will be an example of what I mean.
I choose Knights of The Old Republic for the reason that it made me think about not good or evil, but what are my motives for doing things. Am I making choices because they benefit others or because they benefit me? Consequently it has influenced my choice of education, I went from the goal of Mineral Exploration (high paying, lots of travel, very self-centric) to Earth Science Teaching. There were other factors but I think games like this definitely directed my decision making.
I know there are far more profound games than KoTOR, it was just strangely inspirational.
