Think this would be a good addition to store pages.

We're not able to view content until purchase, and often screenshots, description or a youtube video just aren't enough to gauge a items worth or whether it is an appropriate buy. After all buying from the store is often a case of pot luck in what you will get.
I'd like to suggest adding a review and star rating system on store pages so those who have purchased content can inform others of their purchase and experience with them.
It'd give us an idea of the quality and value for dollar content gives, and whether to take the risk of purchasing an unknown.
It'd be helpful to both customers and the seller alike.

This is being considered internally at the moment, we will work something out.

Awesome, look forward to its implementation.
