As Out of Cards isn't an hearthstone only site as some competitors of old, I think that we should change a little how we handle discussion about things that aren't hearthstone related.
How things are now: we have a big section called "Hearthstone" that contains a lot of different things about our favourite game, a smaller section called "Magic the Gathering" with things related to different media (Magic Arena and paper magic, but more Arena of course), a "Fan Creation" section that seems to be Hearthstone related, and an "Off Topic" with a "video game" subsection.
What I propose: while it's clear that Hearthstone is the most important reason people come here, we must say that there can be more. So I propose to change the section Magic related to one called something like "Other Collective Card Game", with a Magic subsection and an other sub section. Maybe now it would be nearly empty, but in future, who knows? Yugioh, Eternal, Elder Scroll Legends, Artifacts, the secret thing I'm working on, there are a lot of CCG on the market people can discuss on.
For the same reason, in the "Fan Creation" section we should have a section for creations that aren't Hearthstone related. I loved how on hearthpwn there were the card creation contest, I know that it's a feature that will be implemented, but there is no reason to stop around Hearthstone. Why not support people who make fan card of Magic? Or Yugioh? Or who want to share arts or code or projects for new ccg?
Both are things that shouldn't go in a "video game" under "off topic" section, that is for things that aren't ccg.
I saw that there are now at least 2/3 thread dedicated to other ccg, so sooner or later it can be something implemented.
