Except, and I'm stunned this is a surprise to some but here we are, not everyone agrees on what's awesome and what's shitty.
So, in OP's case, the people who come here to talk about the nintendo games and then decide to take the plunge and post something are met with downvotes for having the audacity to post in a harmless community that others don't like.
It's lame and makes the fediverse less fun for folks, which is poison for somewhere that depends on network effects.
