I'm one of the chatizens mentioned in the initial question. I'm very much in favour of having a place on Meta where members of this community can find and organize games.
The motivation for this is pretty simple: I find that the members of this community that stick around are generally people that I'd like to play games with. Currently, the only way to organize such a game is through chat.
I find chat to be a pretty limiting vector for finding a group for two reasons. First, there is a very small proportion of the site's userbase that uses chat. I'm fairly certain that there are many RPG.SE users that would be potentially interested in an RPG.SE game, but aren't typically on chat. The second is how localized a chat message is. If I post a message in chat saying that I'm interested in starting a game, it's very unlikely that a chatizen is going to see it unless they're actually in the chat.
Moving game ads from chat to meta addresses both issues. A much larger portion of our community reads meta than chat. In addition, meta questions will occasionally be linked on the main site as Hot Meta Posts, increasing their general-community visibility significantly. Also, a meta question is much more persistent and easy to find than a chat message, especially since searching through chat is so much more difficult that searching through meta.
The primary focus for Meta is to handle general site operations, but it's been used by other stacks as a place to handle various community gatherings. As an example, Arqade has a community-events tag that they have been using for a while for their bimonthly movie nights.
What I propose is this:
As a temporary measure, we allow community-games questions on Meta.
This would work like our experiment with game-recommendation on Main. We acknowledge that an ad for a community game might not exactly fit the mission statement of Meta, but it's also a really useful tool for our community if used properly. We would then allow these questions to be on-topic for a fixed length of time, say, six months, and then we re-assess.
While the game-recommendation tag ended up not being a success in the end, I think it shows that we have the ability to run these sorts of experiments in expanding our ability to serve the needs of our community.
Since we still want to avoid unhelpful or low-quality questions, we would need some additional rules for questions like this to be on-topic. The intent behind these rules is to ensure that a reasonable community member can look at the question and know whether or not they would be interested in the game before responding.
- The question must state what game system or systems are intended to be used. Saying "I'd like to run something either in Fate or Dungeon World" is fine, but "I'll run whatever" is too broad.
- The question must give a brief summary of any important non-system details (like game setting, the software to be used, etc.).
- A method of contacting the game-runner. This doesn't have to be any kind of formal contact info like an email address, but could just be "use @DuckTapeAl to contact me in chat".
- A deadline for joining. There should be a definite cutoff for times when it is appropriate to attempt to join such a game, so that we don't continually get posts on a particular ad, years later.
With such a list of requirements, I think we could have questions like this that have a high quality bar, and can reasonably be used to organize community games.
I don't believe that this would appreciably add to the issue of clutter on Meta. I haven't personally run into any issues finding important rulings on Meta, but I don't think that there will be enough posts of this type to make it more difficult to find things here. Based on the frequency of game ads that I see as a moderately-active chatizen, I would expect roughly one game ad per month to end up on Meta, assuming that more game ads are posted as the idea gains visibility. I count 23 Meta questions asked in the past month, so I don't think game ads will ever be a significant source of Meta posts. In addition, it's fairly easy to exclude particular tags in a search with -[tag], or even hide them entirely if you're not interested in seeing them at all.
I believe that community game ads like this would serve a valuable function to members of our community, while not hindering the normal functions of the Meta site.
