BioShock - Deep Sea Fatherhood

The BioShock series as a whole is about daddy issues really. I can't believe it took me a good while to notice this, but in addition to "there's always a lighthouse, there's always a man," there also needs to be "there will always be daddy issues of some kind."

BioShock 1- Jack and Andrew Ryan
BioShock 2- Subject Delta and Eleanor
BioShock Infinite- Elizabeth and Comstock
