EDGE- We tend to stop writing about games when you start playing them. We cover the announcement, we write previews and reviews, but by the time you unwrap a new game we’ve moved on.

Here, contributor Simon Parkin reflects on the effect the scoring system has on his approach to People Can Fly’s 2011 shooter Bulletstorm.
