Changing the World gets the High Score!

So I consider myself a bit of a gamer. Not a usual gamer - I don't tend to play first-person shooters, I have little interest in big-franchise games (except Watch Dogs, because that's awesome. Oh, and Titanfall) and I'm more interested in art, story and character than gameplay.

But here's the thing: I've been reading about games too. And it turns out, games have the power to change the world.
