IGN: Top 50 Game Developers

[BreakABone]

I'll just say this, I don't like how they did this list since essentially combined a lot of studios that fall under one umbrella (Capcom, Nintendo, Namco, etc) to smaller independent studios which for the most part won't match the pure output. Anyhow, here is their list
