The GoT game was likely a huge money sink for them, super expensive franchise and they had to pay for the likeness as well as some of the voice acting of some relatively pretty big actors.
I dunno why I was surprised by this. The company must have been super mismanaged. I know that it's a lot of hard work to put together a game, especially one with an outdated engine, but I'm really surprised that the games Telltale was putting out required such a big crew.
Once the novelty wore off people stopped buying their games because they were all the same and hardly a game.
So expensive licensing rights, expensive development due to 100’a of hours of voice acting and giving the first chapter for free to hook people in I think resulted in a very poor business model in the long run.
If you played one TTG game you played them all they never really developed their formula so it really bacame stale.
All others were failed financially and did not recoup costs.
