Going outside today, Britons? Do watch for the sky falling. Because Nintendo's dominance over the top end of the charts has been loosened by, of all things, a PC game, of which we've seen maybe 3 or 4 in these charts over the past two years.

Right behind Will Wright's latest is Mercenaries 2, proving that you don't need flashy petrol giveaways to secure sales. You just need some Peter Stormare.
