So, I'm about halfway through Bioshock: Infinite. Here are my thoughts on the game, done Stormtrooper style:
1) It's just as beautiful and intriguing as the first one, and the actual gameplay/physics/whatever the fuck you want to call it is/are top-notch.
2) The game has some serious flaws, namely a slow start and an annoying, moralizing banter that takes place between Booker DeWitt, the protagonist of the game/the man you play, and Elizabeth, the young woman he's tasked with saving from the floating city of Columbia. The slow start can easily be explained away with the fact that I'm a meticulous explorer and thus spent about an hour-and-a-half looking through the city of Columbia before the storyline progressed to the action portions. So, if you're one who likes to race through the game and finish it as fast as possible, you'll probably only experience about 15-20 of minutes of gameplay that doesn't involve shooting. That being said, one of the beauties of Bioshock was its thought-experimentation with the inevitable pathologies that would come about in a world implementing Ayn Rand's objectivist philosophy. In Columbia, we're shown that a state run by religious fundamentalists would virtually be the same as a state run by socialist zealots. While this is as equally significant as the philosophical revelation of Bioshock, its profundity is hampered by the fact that Booker and Elizabeth spoon-feed it to us instead of letting the visuals and political rhetoric of the NPAs (non-playable antagonists) bring us to the same conclusion.
3) Ultimately, Bioshock: Infinite is somewhat of a letdown. However, this letdown exists only in relative terms: had I not played Bioshock beforehand, I would have thought Bioshock: Infinite was one of the greatest games ever made (which it still is when compared to the overwhelming drivel that is released today). Bioschock exists in a class of its own, but so does Bioshock: Infinite.
