Wow, BioShock Infinite looks extremely cool. I was never that enthused about the Rapture underwater aesthetic, but I certianly appreciated it. However, I'm completely sold on a floating steampunk city with robots and old-timey gramophones. I'm especially excited for a some good blimp action. I can't remember the last good blimp scene I played since Indiana Jones and the Last Crusade. The Icecrown gunship battle does not count.
Blimps! (it's a word that is just fun to say)
