I recently submitted a new DLC for this game on Steam. It got denied because the DLC store page had a link to my page on RMN. (Yep, the same link on my parent game, my other DLC, and all my other games that still have this link. How I got past the Steam team from previous submissions is beyond my understanding.)
"because the "Visit the website" link leads to another site selling the same product through a different store. It's not allowed to link to other digital stores from Steam."
Apparently RMN is a store that sells games and Steam is very scared of this. I was going to try to argue about this with Steam, but there's really no recourse for me to do this and it's easier to remove the link (and no consequence or anything to stop me from adding it back once its removed, I'm not kidding, Steam doesn't approve store pages for making tiny changes after approval.)
author=Sgt M What's funny is that itch.io not only allows you to link to other storefronts, but it has a game profile field specifically to link out to a Steam page.
Steam had a part that asked me to link my homepage for my webpage, that's originally why I linked the page. And prior to this denial, all my other pages got accepted. I don't think the reviewer carefully looked at RMN or understood what it was. I have experienced some other inconstancies with review over the years.
itch.io has an option to upload Steam keys, so that when people buy from there they also get a Steam key.
