You know, i've not played Among Us, but it looks like a very fun game and there is a lot of potential in it! And there's one thing that can make the game relevant for a long time: Workshop. If you added a Workshop for people to create content, as hard as it seems, it will make the game very, very fun for long, although it needs a mod to make sure people aren't making inappropriate stuff, an official way for the community to make new maps, game modes, tasks, skins, etc. would be great!
(Btw i'm posting this here again because in the home page looked a bit weird)
