The Blender Publisher is free "close-source", right

But, what I can do with it Can use for commercial products The license key is yet applicable (Individual key limit of 1000) Is the Publisher in public domain

Sorry for my bad english!

Blender Publisher is a version of Blender before it went open source, the only significant difference is that all of the actuators and such work in it thus all of the old game demos work with it completely, and it uses SUMO for physics which is a lower quality physics engine, and of course it doesn't have any of the features developed since it went open source.

The license is free, the key was available for download for free somewhere, but may have been lost in the site migration.

It can be sold (example: If I want sold it, I can?)?

Not I want sole it, but is only for curiosity, and because I writing an article about it and about Blender open-sourced version

Is because it that need know, and also because I want, in future, make games, and sold it, now wich the GPL version not permit sole games with scripts. Please, reply me... Thanks.
