Fable III is a awesome RPG game with an amazing story line and lots of really good features. The game was released in October 2010 on Xbox 360 and PC. 
Pc player could buy the game on the Steam store until December 2013. The decision to take down the game from the story was mostly due to Game for Windows life market place closure. 

Fable III is still available on the steam library of people that already purchased it but no more copy of the game will be available to buy on the platform.

The problem is that among all the great features Fable III possessed,  some of them were linked to Game for windows life, the DLC, the possibility of playing with an other player, the possibility of trading and chat with an other player and also the resolution of some of the quest in the game where you need two hero playing together to resolve a puzzle. 

Fable 3 deserve to be bring back, just like other GFWL game did before. Just a patch would be amazing, please don't do the same mistake as Fable Anniversary by releasing a new Fable III remastered, when people that already paid and still possessed the game still want to play. I know it's possible to bring people back on it, the coop feature, an online working with steam, maybe steam card or achievement based on the actual in-games achievement/trophy can motivate people to try it. 

Propositions : 

• Change all the GFWL features with a steam compatibility
• Add features proper to Steam like achievements or Cards
• Make a bundle with other fable games (?)
• If you release the game as a remastered version give people who own Fable III on steam a discount (?)

Please Lionhead / Steam, envisage this possibility and give it a try, for a 5 years old game, it's still amazingly enjoyable and great ! Don't let it disappear !
