@xianc78 Journalists, by far. Simply because as the Resetera/NeoGAF saga has shown, they have far too much clout and ability to influence gamedevs that none of the other groups do.
Speedrunners stick to their own games, that's why you see so many speedrunning shit like the Spongebob game. E-Sports athletes will only play games if they're "good enough", when the flood of shit esports titles happened many like Lawbreakers bombed (vid related), and CoD became very divisive. Halo even went down the toilet as a result of trying to pander to people without having them play the damn game. Streamer/eceleb cancer can also kill a game if people parrot their opinions, but they can't directly influence them to the same degree as "posting on a message board devs post on".
There was a theory that the whole Ion Fury drama was a false flag troll op, simply because the OP was found to have had an edgy internet past years ago.
