We need a version of "open source" that requires you to pay a reasonable ($60) price to get a copy.

That's kind of against the usual notion of "open source" but it's the only way this would work in e.g. the game industry, as currently factored.

Studios won't pay people millions of dollars to make games if the return on investment is zero other than helping all of your non-open source competitors.

I do think it's doable, but nobody's done this successfully yet.
