Choices involving good, evil and morality seem to be the latest trend in games. In the old days, the only choice you had was whether to use the boomerang or bomb as a secondary weapon in The Legend of Zelda. But times have changed.
At first, the choices were opaque: in Grand Theft Auto III, when not in a mission, you could run around and kill innocent bystanders for no reason. Or you could abide by the law (except traffic laws) and just stick to the straight and narrow. I wreaked as much havoc as possible because that world is a virtual playground and I wanna play! It wasn’t a choice in the way we usually think of them, but it was there for you to decide.
