There’s conflicting messaging on it, some on Steam claim when they implement it that mods quit working, and others claim that just isn’t true… I don’t know as I’m not paying what Capcom wants for some of their games, but I know that it messed up compatibility with the Steam Deck when they added it to Monster Hunters in January.
If I owned one of the games that might get it, I would look into keeping a second copy that isn’t updated though. Or turn off auto-updates in Steam.
It’s what drove me to wrestling torrents, The WWE network was great, it had chapters, and the stuff was easy to find, then they sold it off to Peacock and stuff is hard to find, they have no chapters, they censored some of the old controversial stuff, it’s just a lesser experience than the old Network. I’m very interested to see how it’s integrated into Netflix, and if they move the US to Netflix when the Peacock deal is over.
