Red Dead Redemption hasn't just been the critical surprise of the year, it's also been the retail surprise of the year, publisher parent company Take-Two revealing today that the game has shipped almost 7 million copies since May.

As part of its financial results reporting from earlier today, Take-Two say that the game, developed by Rockstar San Diego, has shipped 6.9 million copies worldwide.

Now, "shipped" does not mean "sold to customers", it just means "sold to stores". And we normally only care about the latter. Still, subtract the copies on the shelf and there would still be millions sold (surely at least 5-6), meaning you're looking at very healthy sales figures for a game that, prior to release, very few would have guessed would do that well.
