BioShock Demo is up on Marketplace

I don't think enough can be said about the amazing architecture and atmosphere of the game. It's really stunning.

Some more reviews are coming in:

"This is the really bewildering thing about it: it succeeds so stunningly on three different fronts. Not esoteric ones, either, these are the big challenges developers have been struggling to master for decades: narrative, emergence, a sense of place. If another game did just one of these as well as BioShock, it would immediately qualify as a classic. When a game comes along that does all three, we can only be baffled and thankful."

"And with that out of the way, all that remains is to insist that anyone with a PC or a 360 goes out and buys this wonderful game on the 24th of August (or sooner if you happen to live near the street date-breaking US retailers), and send a message to the entire games industry that this is the kind of game that people want. BioShock is the ultimate rarity: not only does it live up to its lofty promise, but exceeds it through simple, old fashioned talent and imagination - not to mention verve, style,class, wit, and sheer bloody-minded ambition. It takes the tired, worn-out FPS genre by the scruff of the neck, reinvents and bend it out of shape in such a breathtaking fashion that it's going to take something very special to top this in the months and years ahead. For a game to be so outstanding in one department is one thing - to manage to tick every single box from graphics to audio to gameplay depth to atmosphere and innovation is pretty much unprecedented. Seriously - if you don't find something to love about BioShock, we'd recommend a trip to the nearest doctor to check if your heart's still beating."
