We miss out on some of the great potential of this medium if we focus too heavily on the real. We have the power to create entire worlds—isn’t using this power to create a shadow of reality a bit of a cop-out? And really, it’s only a conceptual cop-out. In practice, reality is quite hard to recreate. This is why the lushly-detailed world of Avatar’s Pandora is so compelling to people. It’s new, but recognizable. It’s compellingly different, but not alienating. This is the potential that exists within games.
