From what I've read, the PC version is not a port, it's completey
different from the console version. Two different developers, two different games:
Internal THQ group Heavy Iron Studios developed the console versions. Taking the form of a 3D action platform title, the game puts the player into the role of all four members of the Incredibles family, each of whom has his or her own levels that are tuned to his or her special power. For example, Mr. Incredible's levels are filled with mass destruction, while superspeedy son Dash's levels are built around fast action.
The Incredibles: When Danger Calls for the PC/Mac offers younger gamers experiences of their own, with 10 levels full of minigames based on the film's characters, settings, and events. It was developed by Imaginengine. The GBA version is developed by Helixe, and Beenox adapted the console game to the PC/Mac.
I was thinking about picking up the PC version... until I read this. :?
