Nothing wrong with having both the forums and a Discord, and people can stick to the one they prefer (after all, there is an IRC that I'm not sure anyone born past 2005 even knows how to use). The Discord could be for the average player, and the developers who have it (I know you do, as well as vladislavbelov), while the forums are for more technical discussions, and for contacting the other devs.

¿Puede desarrollar más esa idea? por favor ,me ha dado curiosidad .

-Si , esas mismas armas, en forma de triángulo, pensé que como se usaban en el periodo anterior , las habría en el siguiente pero hechas de hierro. ¿Qué es un "Picks"? el traductor dice una cosa muy extraña jajaja.   Disculpen las molestias*

What I meant with that, is that short content can be recycled that way between those social networks, not between YouTube and Instagram. They should have different technical and creative formats, because target is completely different. Reels are practically the same as YT Shorts and TikToks, they have vertical resolution and work way better than posts in terms of reach and retention, which leads to account growth. TikTok and YT Shorts are a possibility that can be considered furtherly, with a well-based YT channel and Instagram account. I do not think that developers are targeting a smaller fan base if they are opening Instagram accounts of the game. It would be even better to have a news section in-game, in starting menu. I detected bigger issues, YT channel has not SEO neither. In a few words, videos are not optmized to be watched by a target public. They do not even have a mianiature, descriptions are too vague: I am gonna give you an example of an attractive game update video: Interesting title, advances the most important aspect of the update. Has a dedicated miniature and describes well what is the video about. This video currently has 2 views per hour, outperforms other videos in the channel by 3.6 times and was published a year ago, it is a success. On the other hand, the 0 A.D. one has a generic title, does not give details about the update nor generate interest. Has no description, with a generic miniature. Has 3 views per hour. The only good thing is that views are proportional to the previous video, which means it wil reach around the same amount of views in the same time. But players are missing it, it is the most important update to day and it looks like any other forgettable news. Interaction is precisely the point. Having a text conversation with devs on a Discord channel feels closer and more responsive than posting a forum topic and hoping someone read it one day. In my opinion, this is a critical issue for game popularity, and if devs want not to move to newer spaces, they will struggle to find donators to make the game better, as I have read it is not published on Steam because playerbase must be kept small due to multiplayer server capacities. So community size and managing is probably limiting game potential.
