Here's my super short spoiler-free review-

BioShock Infinite is like winning $10 million in the lottery, and then realizing you only get $5 million after taxes.

Or, more directly, it is still one of the best games to come out in years, but only half as good as it looked in the trailers.

Things worth discussing- The Luteces, The Racism, The Difficulty, The Angel Columbia, The Which-BioShock-is-the-best? (Columbia vs Rapture, Plasmids vs Vigors, Gun inventory, health packs, ), The Ending Generally, How-Would-This-Look-In-Oculus-Rift?, The Thing After The Ending, What Happened to the Game in the Trailers?, Does the Xbox version actually look worse than the Xbox version of BioShock 1???, Why the cutscene when you die doesn't make any sense, or maybe it does, Will the Circle be Unbroken?, Elizabeth- revolutionary AI or more of the same, etc.
