ever conceived." Reviewers did highlight a few negative issues in BioShock, however. The recovery system involving "Vita-Chambers", which revive a defeated player at half-health, but do not alter the enemies' health, makes it possible to wear down enemies through sheer perseverance, and was criticized as one of the most significant flaws in the gameplay. IGN noted that both the controls and graphics of the Xbox 360 version are inferior to those of the PC version, in that switching between weapons or plasmids is easier using the PC's mouse than the 360's radial menu, as well as the graphics being slightly better with higher resolutions. The game has been touted as a hybrid first-person shooter, but two reviewers found advances from comparable games lacking, both in the protagonist and in the challenges he faces. Some reviewers also found the combat behavior of the splicers lacking in diversity (and their A.I. behavior not very well done), and the moral choice too much "black and white" to be interesting. Some reviewers and essayists such as Jonathan Blow also claimed that the "moral choice" the game offered to the player (saving or harvesting the little sisters) was flawed because, to them, it had no real impact on the game, which ultimately lead them to think that the sisters were just mechanics of no real importance. Daniel Friedman for Polygon concurred with Blow, noting that the player only loses 10% of the possible ADAM rewards for saving the Little Sisters rather than killing them, and felt that this would have been better instituted as part of the game difficulty mechanic. Former LucasArts developer Clint Hocking wrote a noted essay that claimed that BioShock exhibited "ludonarrative dissonance" between its story and mechanics, as while he saw the story as advocating selflessness in helping others, its gameplay encourages what he views as selfishness by preying on Little Sisters. Awards At E3 2006, BioShock was given several "Games of the Show" awards from various online gaming sites, including GameSpot, IGN, GameSpy and GameTrailers's Trailer of the Year. BioShock received an award for Best Xbox 360 Game at the 2007 Leipzig Games Convention.
