Can anyone give me a comprehensive list of notable video game developers? All I know is that are too many that have only made one game and others that have made many. I was thinking by revenue or games.

Atari Bethesda Game Studios BioWare Black Isle Studios Blizzard Entertainment Brøderbund Bungie Capcom EA Canada EA Digital Illusions CE Enix Epic Games Game Freak

HAL Laboratory

Insomniac Games
Intelligent Systems
Irrational Games

This lists top 25 by revenue given a year. Companies, not publishers.

Wow! O _ O Nicely done nihilist... That's quite a list. Though I wouldn't suggest just ignoring the smaller the developers! They often contain new gaming concepts and ways of playing a game. :)
