Bioshock is, by all accounts, an incredible-looking story-driven shooter with deep gameplay for the Xbox 360.

So is Halo 3.

The major difference between the two of them-- on top of Halo's multiplayer, saved films and map editing features, is that Bioshock is out already, and Halo 3 is not.

Despite this, on Amazon.com, two editions of Halo 3, the regular and limited, are both outselling Bioshock, according to Next-Generation. That's crazy.

I don't see this as a slight to Bioshock at all, just a testament to just how much anticipation there is for Halo 3.
