Depends on what you mean by "normal". If you create a space with no community or moderation, yeah, it's normal for that to be how it ends up.
PC Gaming
Rule #1: Be civil
Rule #2: No spam, memes, off-topic, or low-effort posts/comments
Rule #3: No advertisements
Rule #4: No streams, random gameplay videos, highlights, or shorts
Rule #5: No erotic games or porn
Rule #6: No facilitating piracy
Rule #7: No duplicates
Pretty normal for most gaming communities steam or otherwise.
They all devolve into that because, well they're games, not a whole lot to really talk about once the initial exploration of mechanics happens and then it falls into a cycle of other stuff, patch comes, discussion happens briefly, then back to other stuff. Rinse, repeat until the game does or the developer does something to piss the community off.
In my experience, yeah its normal. Have you seen the top rated comments with all of the emoji reactions? Those are rewarded with Steam points that can be used in the points shop. Jesters are hella easy to farm.
Like, you're complaining that there isn't enough about the game? I mean, I see useful content on plenty of games.
Are you selecting "Discussions", which is where the forum for the game is, or just looking at the top-level page for the community hub?
Like, this is the Rule the Waves 3 community hub.
