Video game adaptations are very difficult, actually, make that near impossible to get right. Tons of studios have tried and failed and even projects that seemed like they had lots of potential (we're looking at you, Warcraft and Assassin's Creed) ended up being pretty big disappointments. That's why we're quite surprised that BioShock, a video game series that truly does seem perfectly suited for a silver screen adaptation, has never made it to cinemas.
