High Voltage Software

One of the only independent game development companies which has managed to receive large contracts, like the family guy games and other big commercial projects. But then again, 130 staff members at this company doesn't exactly make them all that small. Right now they are focusing mostly on nintendo wii games.

Some other games they've produced include the simpsons racing game, duck tales 3d, and quantum 3. They are based out of Chicago Illinois, and have been in the business since 1993.
