"This game is no longer available for sale on Steam". No big deal, right.
Ok, fine, but it doesn't imply the servers going down and the title becoming unplayable...
Then 2nd message:
"Please note this title won't be accessible from <date>..."
Once again, accessible doesn't imply "the game won't start, thanks for the monies".
It's a bloody shame that I can start any games from the 90s on an emulator and they run just as fine, even content heavy. While these titles are completely riddled with DRM and screw you over after X years.
Publishers need to come clean, and after years of milking the cow, they must have a plan allowing paying customers to play the title they've been enjoying all these years. Otherwise, they should be forced to include the verbiage at release date "This title will stop working as of <date in the future>".
This kind of nonsense only promotes cracked games.
