Please add refund option

There should be a refund option like steam has, where after x amount of hrs played, or time passed, one cant refund the purchase. This is extremely needed, you don't allow word reviews of these add ons and textures and when one purchases anything on the market place is not a guaranteed that the customer will be happy with that purchase or if it even will play nice with other add ons. So, since you don't allow word reviews, then the obvious move would be to add a refund option with a time period for a refund. Another good option as well is to add a compatibility list where users, that bought the add on, can report which add ons of theirs worked with that particular add on being sold and which did not to better inform future buyers.
