So as long as you purchase the interactive license, you can use these models for commercial use?...

Or is it way more complicated than that, and situation differs for each model that can be "bought".

the interactive license is so you can use the models in a game environement for a commercial game. You can use any 2D images, animations or sprites anyway you want with out any license. You cannot use any of the models at DAZ for game mods or to share or sell any part of them. Hope that helps.
