While BioShock 2 hasn’t received the same critical acclaim that the first title did, it has still received some pretty damn good reviews. And reviewers apparently aren’t the only ones who like the game as it was just announced that BioShock 2 has sold 3 million copies across the Xbox 360 PC and PS3.

That’s not all though, Take-Two also took the time to let us know that Grand Theft Auto IV has sold 15 million copies worldwide since its release.

Some pretty big numbers here now I just wonder how much their sequels will sell.
