As far as I know, all the marketplaces have a license agreement that forbids appropriating a mesh in any way and forbids redistribution.  Now, of course, a merchant or freebie provider could create a purchasable license (or what have you) for use of their models as a resource, which is basically what is happening here :)

There should be some clarification as to which native Poser meshes can be used as resources, if any at all.

BTW, I think the whole Game thing is an excellent idea as a whole :)
