I find it weird to rank this higher than the original BioShock, because that game was far more interesting in the setting and the story. I just had a better time with Infinite because I was actually able to finish it without problems. The gunplay is much better and the story is easier to follow within gameplay.

That aside, it's great to see a sequel that can do something unique rather than just doing more of the same thing. It's still easily one of the best games of the last 15 years.
