List of Telltale games that are unavailable for purchase on Steam (and where to find them)

Update: Somehow I missed Telltale Texas Hold ‘Em which is still purchasable via Steam, that's been added to the table. Also I removed the Humble link to The Wolf Among Us because it's no longer available.

WinGameStore no longer carries the following games (links removed):
The Walking Dead
The Walking Dead: 400 Days DLC
The Walking Dead: Michonne
The Walking Dead: Season 2

Also Hector: Badge of Carnage price is $14.99, not $19.99 (price corrected)

Added links to key resellers via gg.deals and links to Epic Game Store for The Walking Dead games

Telltale's The Walking Dead games have returned to Steam! Sorry I'm a bit late to update but they are officially back with Skybound Games listed as the publisher. Also I've cleaned up the main post and moved the list of available games into the main post so people can find it easier. Take care gamers <3

Steam no longer sells Telltale Texas Hold'Em and Strong Bad's Cool Game for Attractive People.
WinGameStore no longer sells Back to the Future: The Game, Jurassic Park: The Game, and Tales from the Borderlands.

Both lists have been updated, and I added an article about LCG Entertainment acquiring Telltale Games

Every Telltale game that's still on Steam is 50% off except for The Walking Dead and Sam & Max games.

Both Telltale Batman games got DLC back in December, added to the available list

WinGameStore no longer sells Tales from the Borderlands, link removed from the unavailable list

This thread is pretty useless now. Of the games that remain delisted or purchase disabled, I doubt they will be coming back. If you are looking to buy any delisted or purchase disabled games, just search GG.deals like I did. I'll be removing the key reseller prices from the table above, I hadn't been updating them often anyways.
There are no signs of the untitled Game of Thrones sequel or the untitled Stranger Things game that were being worked on before the closure of Telltale Games.
The Wolf Among Us 2 has EGS logo in the trailer, likely a 1 year exclusivity deal. The Expanse: A Telltale Series has no platform logos in the trailer but I am expecting a similar exclusivity deal. Both games are planned to be released in 2023.

Strong Bad's Cool Game for Attractive People: Season 1 is now purchase disabled

The Expanse is the newest release from Telltale Games. It remains exclusive to Epic Game Store for now. I will add it to the list if/when it gets a Steam release.

A Steam Store Page for The Expanse is up.
No release date so far tough.

does the Steam DRM key of Jurassic Park: The Game for Mac allow me to download and play it on Win, can I activate it while using Win version of Steam?
