The onus is on the developer to differentiate between "making a game" and "making a game sell". Jumping platforms because you failed is throwing away all the experience and knowledge you now have for an unknown platform. Developers who can't figure this stuff out just don't get to make games for a living.

Startups face the same problem and almost exclusively fail for the same reason. And businesses in general. And authors. Musicians. Actors. Artists. Singers. The list goes on and on. You have to be good at what you do to make it your occupation.
