I miss a lot of those and even if they're unplayable I'm glad they're still in my Steam library, like Ghost In The Shell: Stand Alone Complex or Brick-Force. The games weren't exceptionally good or fair with microtransactions (looking at you brick-force), but I still miss them
I also often wonder why singleplayer games get deleted from Steam, though. What do companies like Telltale have to lose from leaving Poker Night at the Inventory on Steam? Reputation? It was pretty good, the entire playerbase knows it exists and it's not like Telltale has to pay monthly - the game would just continue raking in chips, whatever the amount it would be a net positive.
What do flashiis think, and what are some of your favourite deleted games, still playable or not?
