I’m assuming that most think that the marketplace is just for those looking to make a commercial game to sell where I’m thinking that it’s more of an opportunity for those interested in making a game having access to resources that they themselves do not have the skill or resources to do it on their own.
I’m also assuming that there are more individuals who just what to make a game, any game, as an experience than there are those looking to do it professionally but already have the ability to produce quality as in there is more who play the game of golf for the enjoyment and have the skills but with no intention of doing it professionally.
As for junk showing up with a price tag I don’t see someone paying 20 bucks a month just to upload junk being the case and along with a review process on Epics end of actually reviewing what is submitted as to fit to finish in the case it’s a price tag that should determine value and worth is more than enough of a safe guard. The only thing I would add would be at least an in-store credit if something does get through that is no usable.
On the other hand if someone want so give something useful away for free then there is no risk of buying junk.
Give it a year and see what happens.
As for one game looking like another using the same assets it’s only noticeable by those looking for recycling and next time you play COD or BF count how many times the same door is used over and over again and if hero stuff does get noticed so what. How many fan flicks based on Star Wars are there where the same ideas, concepts, and content is use over and over again and no one really cares beyond being entertained?
