Boomtown writes: "No rivalry in the world of gaming is fiercer than the one between competing football franchises. It almost mirrors the strength of feeling people have for their club. Crossing the divide to support another franchise is a relatively rare occurrence. There are two major derby matches in the football gaming calendar and they feature a bitter enmity which has built up over the last few years. The first is Pro Evolution versus FIFA and the second is Championship Manager versus Football Manager."
