Well if it isn't possible due to resources, then I digress. What I had been saying is only how the situation appeared to me. I thought Larian had grown by now, especially with the release of Divinity 2 being multi-platform and all.
As for the availability of Divinity 1, there are actually two different versions you can buy off Amazon new. One is jewel case only and other boxed. Both of them are under $15 too.
