LMAO I can promise you, they worked at one point, and I did play them. I know apex doesn't work in Linux now because the devs purposely decided to break Linux/Proton compatibility, and I believe Warzone is the same way. Battlefield was a buggy mess and not very fun to me when I played it, so I didn't really keep up with what happened there, but I wouldn't be surprised if that was dev incompetency as well. Why blame Linux when it's the devs of those games that are breaking compatibility, either purposely or out of incompetence?
