Regular Price:


Thousand Threads (formerly Great Cascade) is an open world game where characters remember and react to the things you do — where your actions matter.

Maybe you deliver an item for a guy. He gives you a reward and likes you a little more. Or maybe instead of delivering the item, you sell it to the highest bidder. Now the guy hates you. He tells his friends and they hate you. You're rich, but on the run.

It's not a morality system. It's not a scripted story with branching paths. It's a system of cause and effect. Characters have unique personality traits, memories, and goals, so they act and react differently. Your actions build your story.

Give, take, save, kill, inform, hide, be loyal, betray. Do what you want, and deal with the consequences.


Thousand Threads began as a bunch of ideas on dynamic character AI. It was fueled by talks from Clint Hocking on emergent gameplay and frustrations with Red Dead Redemption (one of my favorites) forcing me to kill folks for no good reason, or failing missions for killing the "wrong" person.

Real work began mid-2014. Character AI was the focus for the first year. Once I had a solid foundational system (oh, hey this works), I began on the visuals. I opted for an art style that I could execute relatively quickly and was somewhat in my wheelhouse.

Thousand Threads is my first big game. Sinking so much time into a single project can be scary, but I'm really proud of how it's shaping up.


  • Open world, open story, single-player.
  • Characters remember and react to the actions you and other characters take.
  • With every new game, the characters' traits and relationships are randomized, so you always get a new experience.
  • Beautiful landscapes to explore.

    - Jack de Quidt, Waypoint
  • "...it looks really cool."
    - Nathan Grayson, Kotaku
  • "'Things go wrong' is one of the best genres of videogames. Thousand Threads is an upcoming open world game that seems to embrace that philosophy, if the developer’s attempt to create a video demonstration is anything to go by."
    - Brendan Caldwell, Rock Paper Shotgun
  • "Even outside of the game’s mechanics, we’re interested in its visuals; they’re simplistic and bright but extremely pretty and considering it’s coming from a one-man development studio, [Thousand Threads] looks incredibly impressive."
    - Emma Boyle, Gadgette
  • "Perhaps most striking about [Thousand Threads] at first glance is its starkly simplistic, low-poly art style."
    - Caty McCarthy, Kill Screen
  • "I feel like "open world" and "your actions matter" have lost most of their meaning, slowly becoming buzz words in the realm of games press. This trailer for [Thousand Threads], however, gives those words some serious oomph."
    - Lena LeRay, IndieGames
  • "It’s a simple cause/effect, being bad and getting found out leading to an angry mob, but it hints at a richer world not defined by a story but the scenarios you create. The art style is gorgeous, too."
    - James Cunningham, Hardcore Gamer
  • "Seamount Games blessed our eyes..."
    - Future Beta Gamer
