The key question is whether investors will buy into similar projects in the future. Telltale's bankruptcy suggests ipso facto that the market for the interactive narrative subgenre is exaggerated. If the premier studio for such content with access to powerful IPs can't stay afloat, it has a chilling effect.
The concepts behind their games will live on, but likely as a niche. It's telling (hurr) that there's only been one notable success in the genre (Life is Strange) outside of TTG's works.
At the end of the day, this entire saga can be stripped down to a classic investment bubble.
Telling.
Aside from that, I mean, if we're REAAAALLY to get our game nerd on, Telltale's hardly the first to make talking simulators with minimal if any gameplay a thing. There was a game on Newgrounds a century ago where you played as a scientist who caused the end of the world and had seven days to try and fix it. I don't even remember the name. Mostly an exploration of a story and it's characters, and it even had one surprising bit of gameplay where you had to avoid getting a knife in your bearded face. Hate Plus even made you bake a cake for a virtual waifu for 100% cheevos.
Telltale just made bigger games. Bigger budgets, established IPs, and bigger profits, too. I think the genre will live on, we'll just get more Doki Dokis and less Games of Thrones. I mean, it's kinda reasonable. A text based narrative is always gonna be cheaper to make than actors or fully animated cutscenes. It's also not completely FUBAR'd if you have to go through, let's say, a single re-write. Which artistic projects often tend to go through.
It happened to Team Bondhi back then. Cutting edge facial recognition tech, established or modestly talented actors, an ambitious script, and making this become a reality forced everyone in the studio to perpetual crunch time. Now it's happened to Telltale too. It's just something about big scope artistic games. To the head of the studio, it's his magnum opus. To the guy making you a nice model of a hat, it's just a 9 to 5 job. And if he has to stay overtime every day, making you ten million hats to choose from, he's probably gonna resent and or sue your ass for it.
