They were just there!
You could do multiple things actually.
1. Turn off Steam notifications.
For those worried about "muh immersion" this should be the obvious solution. The thing more disruptive than some little notification after beating a stage is seeing the same persons name pop up three times in an hour letting you know they're on Counter-Strike.
2. Use the program SAM to unlock all achievements. If everything is unlocked, you get no notification. Then you can delete them all afterwards or not care about them.
3. Play your game in offline mode.
Not a solution for all games bu it is for some.
fr33kSh0w2012: Well actually I can still download the mobile games through Google Play look up telltale games in Google Play and they all come up well most are the first episodes anyway, I'd have to get a blue tooth controller to play them though as screens are too damn slippery and have no tactile feedback which feels weird.
They're all pretty much still available everywhere, not sure why you think the Google store is some worthwhile metric of a games status. The only games you can't find is Wollace & Gmit because that license expired forever ago and Poker Night 2 presumably because they don't want to deal with a lawsuit if the licenses from that game expire and whoever they leave to handle their IPs digitally forgets to to tell distributors to remove it.
