When Bioshock was released in fall 2007, it was a groundbreaking game. With its unique blend of art deco-meets-Jules-Verne visuals and Ayn Rand-inspired philosophical debates about the nature of man and free will, it quickly became a classic. It was a great game, but a self-contained one. It wasn't designed with a sequel in mind and with creator Ken Levine moving on to other things, there was a lot of skepticism regarding the viability of BioShock 2. Thankfully, the fine folks at 2K Marin have utilized their legacy of BioShock lore to craft a fine sequel that enhances the series.
