Even so, making a game is expensive, time consuming, and risky… so you don’t want to do that.
… but if you made a machinima building platform, you could go to all the studios and gamemakers and say, drop all your game assets in this software that is built on the same platform as your games and develop scripted/interactive content based on your existing IP. It’s another revenue stream for them without have to start over.
The interface would look like flash/aftereffects and would control object tweening and animations, sound cues, camera and lighting keyframing.
Then on top of that, you build the netflix for machinima. real-time rendered & streaming content based on the exact assets of the game. Perfect for Hollywood movie game properties.
