Sky Kingdom Games is releasing a solo/co-op adventure game for 1-2 players on September 10. As a member of The Isofarian Guard, you travel around the land of Isofar, fighting off enemies and upgrading your skills and weapons along the way.
The game uses bag building as a mechanism, with plastic chips instead of cardboard tokens. There are minis to represent the heroes, and the company has partnered with Forteller on the voice narration of the story which the player can listen to through an app. (They have posted a sample of the story on Soundcloud).
The player has the option to follow the story path or go around adventuring as they wish, open world-style.
Update August 27: The creators have posted a Kickstarter Preview.
