My team designs tabletop pen & paper RPGs and our community is mostly based around Discord. It's the one communications platform we are constantly monitoring. The other platforms (Twitter, FB, forums, etc) we check several times a day. We have several places we sell our PDF currently, but would love to be able to sell it through Discord as well to enable instant role support for betas for modules.
Please consider allowing the sales of other electronic products that count as "games" rather than just video games.
