While the NPD Group has ceased providing weekly sales charts for the boxed-copy PC market in the US, it still hands out its monthly - and often hilarious - lists. Let's look at February's.
It's not until you look at these charts that you realise that PC has been having a big couple of months.
I've got to hand it to Heavy Rain. Or Sony's marketing team. Although I thought the game was pretty good, I also thought it would be a tough sell to Average Joe. Guess not, since it's gone #1 in the UK.
Perhaps because it features environments that are wet, rather than covered in ice, Britons flocked last week to stores to get hold of BioShock 2, which has promptly knocked Just Dance from the nation's video gaming pedestal.
Space and laser guns feature prominently in this week's PC sales charts, last week's consumers opting for aliens and bright-coloured uniforms over olive-grey outfits and the real world.
Just Dance ahead of Mass Effect 2? Sort it out, Britain. I don't care if you have to hit the streets shouting, placards in hand, you sort this out.
Collaborating like they do in times of great need, market research companies The NPD Group (North America), GfK Chart-Track (PAL) and Enterbrain (Japan) have combined to bring us the five best-selling games in the "world" for 2009.
The PC charts were last week dominated by the likes of Mass Effect 2, Battlefield Bad Company 2 and Star Trek Online. No surprises there. So we'll instead focus our admiration on Tim Schafer's Psychonauts instead.
Just Dance's reign of terror has finally come to an end, BioWare's Mass Effect 2 cruising straight into the top spot on the British charts.
Not much has changed in a week in the UK. Wii games keep on selling, Modern Warfare keeps on shooting and Just Dance just keeps on dancing.
It seems our warnings were for naught. And now Britain suffers, with Ubisoft's Just Dance the best-selling game in the country.
Look, Britain. Pull up a chair. It's time we had a heart-to-heart. About Just Dance. And how it's getting dangerously close to being the #1 game in the United Kingdom.
After a Christmas break, we're back this week with some PC sales charts, outlining some of the big sellers (or at least big revenue earners) of the new year period.
Finally, a little variety in Britain's sales charts, as the PS3 version of Modern Warfare 2 and FIFA 10 make way for...oh. Just Dance, for the Wii. Way to go, Ubisoft. Way to go, Britain.
Is there an echo in here? I only ask because last week's British sales charts look an awful lot like this week's British sales charts.
In the penultimate holiday season charts, there was only going to be one system dominating the top 40. And it's not the Xbox 360. Not the PS3, either.
Not going to talk about the top titles this week. Instead, I'm going to talk about a series that isn't even in the charts, a series that even 2-3 years ago would have been challenging for top Christmas honours.
Britain looks set to party like it's 2008 this Christmas, with the weekly sales charts headed by Wii games after what seems like an eternity of 360/PS3 domination.
Big surprise this week, as Modern Warfare 2's cross-platform domination is abruptly ended after only seven days, with the PS3 version nudged aside by a stealthy, Italian newcomer.
