Yeah, you're right. Geez, I thought Mind Game, Tekkon Kinkreet and Genius Party were all from then. Were they always this small or does their reputation just precede them? In my brain, their output was always more quality, less quantity but at least on par to Madhouse and Production I.G....
Studio 4C is a small studio which focuses on both creative productions and cash-in collaborations. They fund most of their operations by working on coordinating and producing stuff like Animatrix, Gotham Knight, Halo Legends, Thundercats, etc. They also do quite a bit of animation for various videogames. They also produce a ton of short animations, commercials, music videos, etc for various companies.
They're nothing like Madhouse or Production IG at all. Those are big businesses. Well Madhouse was a big business. Now it's soon going to be a dead business.
