MTV's Multiplayer Blog has a chat with Dorian Hart, the designer at 2K Boston that gave us the pipes-like hacking mini-game in Bioshock. The two of them discuss the reason we direct blue liquid to win, the fan reaction to the game, and the value mini-games bring to their 'parent' titles. "I suppose it certainly gives the game an extra dimension: something else to do other than shoot. In a shooter, even a shooter that has small variance in how the game plays out, the number of verbs that you actually use in a given 10 minutes, half an hour, an hour of gameplay is pretty limited: you have a gun; you shoot it. Having a mini-game just gives the player a different thing to do, a way to break the player out of a rut they may be in, in how they're thinking about what they're playing. It engages a different part of their brain. As long as it's not too onerous or forced upon the player too commonly. They say, "Variety is the spice of life," and I think that applies in this case. As long as you don't make it an essential, unavoidable, too-important part of the game, because people are expecting a shooter."
