One point I'd like to make is that the study of economics is hugely, fatally flawed. I'm talking generally now, not about LFS. Classical economists simplify a problem down to a few things, so simple that it has no relation to the original subject. Then they do some questionable mathematics based on that, then apply it back to the original situation that is no longer applicable. The result: DISASTER! And to be quite specific, these classical economists who think that "economic growth" is always a good thing. This is based on the assumption that humans are a tiny force, on a planet of infinite size, which can accept any amount of pollution we throw at it and can provide infinite resources. It's complete rubbish, but this is still the mainstream economics that informs most economists, politicians, press organisations and the general public.
Economists have a lot to answer for, including the destruction of the natural world that supports all life as we know it. But they aren't answering. It's too complicated to face reality.
Anyway, that's really off topic, other than the point that to be knowledgeable about economics makes me think that someone is more brainwashed, and less informed than someone who has not studied economics.
Back on topic, copying Steam isn't necessarily the best approach. I believe their sales models are more 'classical' as in, sell as many units as possible, milk that cow as much as you can, then release Version 2 of the game, and milk that cow again. It's not related to the LFS model where people give us a tiny payment and we provide them free updates and support for the life of the product. It's different.
