Not sure what Half Life 2 is doing on there, pretty sure Valve is fully in control of that one on PC at least. Didn't EA publish the PS3 version of the Orange Box? I'm guessing that's for a console port.
Also, Biomutant? That only just came out like two years ago. Not sure what the online features are for that game though, I thought it was singleplayer.
This is all just another reason why I don't buy games where online multiplayer is the main selling point of the game. I might not even get around to playing it much before that feature is removed.
Old PC games with dedicated servers are still (and always will be) playable online, while games from a couple years ago have their centrally-managed servers taken offline. People are still playing Doom, Quake, and Unreal Tournament while games from this console generation are already unplayable.
