Stupid as all those people building games with Unity? Or all those people who used to use Unreal/UDK before v4 while there was no source code available?

Anyway not here looking to start a flame war. My point was that the product can be good or bad and it doesn't have anything to do with it's source code being available or not.

My 5c. Everyone feel free to disagree.

Both Unity and UDK recognised the benefits of open source, and have OS components.

A product can be good or bad without OS. So long as you can deploy what you make with it effectively.

Sometimes that means mindshare, like UDK and Source.

Sometimes that means complete decoupling tooling from code like Sublime and Atom.

Sometimes it is more about the deployment, like Visual Studio and Unity.

However, to stand out, this product needs one of the above.

It's new, and doesn't seem to be backed by a big name, so no mindshare yet.

So they need to somehow make devs want to use it for their code. A nice experience is usually not enough.

An OS community, or a fantastic cross-compilation strategy are the only two things that I, personally, have seen work.

OS seems to be the easiest of the two.

While I side with your central argument, there are numerous cases where the above is absolutely enough.

Games is one kind of software where you usually won't expect to keep your code base maintained 10 or 20 years from now. So far for the "stable platform" argument where you as a user wouldn't want anything less than open source code, unless forced to use proprietary code for external reasons.

There might be a cost/benefit analysis where some closed platform is extremely far ahead in every other aspect, but you should be very well aware of the risks of being tied to that platform.
