a legit digital market for players to sell their digital Games created by and under Xbox...

isn't Xbox planning on creating a market for player to sell their digital games under Xbox control?? because you can really feel the need of this...
idk why they haven't create one yet, it could benefit them too, they can take an amount of percent fee over each sale, it's a win-win, for everyone.
for example, i have a game's digital code to sell (Star Wars Squadrons) and some other games bought on my account that i like to sell them and there is no legit place for me to sell it/them without worrying about "do i spamming", being against company's
policies or fear of my account getting banned in social networks, you see what I'm saying? you see the lack of what I'm talking about? do you feel the need of this as well? so please like, comment your opinions and your thoughts on it and spread the word so
Xbox could hear it...
thank you for your time
