You are feeding money into a thing with massive marketing engines. It's not just say, radiohead, and their cheerfully offbeat marketing strategy. It is roomfuls of people who have nothing to do with any of the stuff you like who are arguing over the best way to get your cash off you sooner rather than later. Those are the people you are paying. Not radiohead, but the people who make shit radiohead t shirts and sell them on amazon.
Hang on, in answer to your question, I wouldn't. Id make engines, not games. I would need some sort of proof that it wasn't a waste of time before I committed to it.
