Bioshock 1 and Infinite are masterpieces. Period. Bioshock 2 is diverting enough, just expect more Bioshock 1.5 without the same highs. If you want to play it for 12 hours or something, you can, but it's skippable. When waiting 3 years for each game, it was fine, but it probably dilutes the experience playing them all in succession.
Truly, the first and third games are two of my most memorable gaming experiences. The gameplay absolutely holds up. But the world design, twisty story, philosophical underpinnings, sci-fi -- it sticks with you. The final act of Infinite will knock you on your ass and have you diving into articles afterwards. Infinite also has one of the best companions ever.
