Ive posted a new thread on this, as many forums goers checked out the previous thread, but may not revisit.
Initially there was an error on the web page in relation to shipping, preventing customers purchasing the membership, so ive created a new page. Ive also increased the price slightly to $21, a small amount for the entire arteria collection to use non exclusive!.

Therefore Gamestudio customers can purchase an educational non commercial license to access all the arteria3d content for your learning purposes, and game prototyping. After purchase you get access to the arteria3d members area and can download content when you wish, as you wish.

At a time when you release your game, you would only need to pay arteria a fee of $100(reduced from previous post as a thankyou), to use the content commercially.
