I'm actually surprised this wasn't started sooner. This will basically be a discussion for any Bioshock Infinite related.
I enjoyed the game, I really did, but I do have some complaints. I felt as though some elements were underutilized, and despite it being a lengthy game, it didn't feel like a lengthy game (unlike the previous Bioshocks). As someone who followed the the initial Bioshock Infinite announcements I was a little disappointed by the actual game. I went through the whole game waiting for Elizabeth to get her powers (you know, the ones where she gets sicker the more she uses them). The whole skyline system seemed under utilized despite the amount of focus on it in the early trailers. Then there is songbird, who I felt could have played a much bigger role in the story line than it actually did. The handymen seemed to get dumbed down from their original design as well. I would like to have seen more done with the Vox as well seeing as how it played a big role in the story until you jump realities for the first time (another complaint towards the story). Of course the ending is flawed too, seeing as how there are so many different realities, getting killed doesn't really fix anything despite what Elizabeth says.
Enough for the moment
