Don't bother reading D's posts on this stuff. No offense, D, but you're horribly biased and have no perspective because you don't even own a console. Just bow out of this particular discussion while you can.
And before this becomes a sad war of opinions, allow me to state the following from as objective a viewpoint as I can muster:
No matter how great BioShock may be, it's obviously perfectly within the realm of reason that someone may want other games far more than they want *it*. They may not even want it at all! Nobody should tell you that you should believe otherwise. However, I think what you *shouldn't* try to say is that the game is anything less than revolutionary, at least not until you've played it and found that to be the case in your own view. I mean, this is one of the best-reviewed games I have ever seen, right up there with OoT. Seriously, take stock of what the journalists of the game industry are saying. The game has received no less than 12 perfect scores so far from OXM UK, EuroGamer, Game Informer, 1Up, Gamespy, Games Radar, PC Powerplay, GamePro, the Alternative Press, Gamer.tv, Gametap, and Playboy. Obviously several of those publications at the end matter little in the consideration, but still... that's a fucking lot, no? And we're still very, very early in the review running. On top of that, a healthy chunk of the other reviews are 97s and 98s. Half-life 2, with three times the reviews, only garnered 5 or 6 perfect scores in its review run that I can find. BioShock has already doubled that and it hasn't even released.
I hear you, it's all just numbers, and I'm not trying to say that numbers really matter that much. They don't, generally speaking. However, obviously there is something special happening here or you wouldn't see an entire industry of game journalists stand up this way, much less each take the time to try and craft their own individual statements about why BioShock was one of the greatest things that's happened to them in their gaming lives. Do feel free to avoid the game or put it off or even try it and decide it isn't your cup of tea, but at least wait until you've had a chance to try the actual product before you tell the active whole of gaming journalism that they're all seeing something that isn't there, or that the bar doesn't at least *appear* to have been raised. We'll all have to wait until we can experience this thing firsthand to truly know for ourselves, sure, but I think it's safe to say that something rare in gaming must have been achieved here. Don't you?
Evolution and revolution are somewhat arbitrary statements with no actual meaning other than what we personally ascribe to them, so let's not waste time arguing semantics. Let's just agree that it appears something new and different is being done. One way or the other, whether it's a revolution or an evolution, I think it's safe to say that this is something far beyond average, and I think we can say that without stepping on anyone's taste or on the merits of any other game.
