It's easy to read about BioShock and think it's going to be a Deus Ex clone. Heck, we even flat-out asked that of Irrational Games at E3 when we got our private demonstration. The game's played from a first-person perspective. Its story explores the highs and lows of human nature. It lets players make modifications to their physical self or gives them the freedom to not make a single one. Sure sounds like a clone to us. But there's one key difference that will take BioShock above the already-high levels of Deus Ex: an actual in-game ecology.
