As with the several times they tried this before, this is a train wreck of an idea for so many reasons. While I do love the idea of mod creators getting to make money doing what they enjoy, from the consumer perspective this is bound to be awful.. I don't want to have to get nickel-and-dimed by what are essentially third party micro-transactions.. with no grantee that the product I just bought will even work with the others I bought or that they will continue to be supported if the game gets patched a year later. Not to mention virtually zero quality control, leaving users to trust in reviews, AKA other customers who put their money on the line.

And from the mod development side of things, this is going to make building off other mods a complete mess. Think of how many mods you have installed that have had other mods as requirements to work. Are those mods going to need to be bought by the user too? And are the mod creators going to have to set up some kind of revenue sharing with those dependency mods? What happens if a mod developer uses a free mod as a dependency, is that fair to the other mod creator? Do moders have the rights to request their content not be used by other mods? And if so what does that process look like and who arbitrates it? Having seen this tried before, it makes a mess and long term it will stifle collaboration leading to weaker mods.
