After getting Bioshock today and playing it for a few hours straight I realised something which never even occurred to me at first. Bioshock is incredibly similar to System Shock, almost too similar to be a co-incidence. Albeit some things are altered to seem different, but look at the following comparisons: Name: Both end in 'Shock', not much of a similarity but it's a start. Weaponry: All your guns have multiple ammo types and can be upgraded. Research: In SS you researched organs of enemies to gain enhanced damage against them, in Bioshock you take Research Photos of enemies and you unlock extra damage after enough photos. Hacking: Both exist as a mini-game within the main game. Implants: Limited number of slots to put these implants in, each giving you certain abilities, known as Plasmids in Bioshock. Enhancers: Certain items that permanently increase your in-game abilities, called Tonics in Bioshock. The list goes on and on, I'm sure this can't just be a co-incidence, is Bioshock really System Shock 3 in disguise? Is it very heavily influenced? I don't know but I'd love to hear some opinions from you guys.
