I have a process.
An idea that I have typically spends a good couple months tumbling around in my critical thinking cavity, vetting itself as I ride the Duc around the south bay. Eventually though, it will become something I need to put honest thought into, some of its features will need proving and I’ll need to bang out a few prototypes to see how feasible things are. Ill spend another couple months jotting down ideas and trying to hone the idea down, paring off the silly and unnecessary details so I can handle a 5 minute pitch and probably build out a team that is interested in the project.
When I saw Gravity, it was a must and I was immediately working towards piecing together the narrative. Months later I met a couple folks on the UE4 forums and we did some discussions about collaborating on the project, as we had very similar ideas. And months later, it is shelved.
