I checked TSI Games facebook page. The most recent activity from TSI is a response to this question asked in November 2018: “Sad that 7DS seems to have dropped off the face of the earth. Motivation-based rewards for character personalities would have been fascinating.”
TSI responded with “It’s slow going but not forgotten.”
Their response on FB to similar questions over the past couple of years has always been that the game is not canceled but progress has been very slow and they have no news to share. I can only hope that the lack of details means they are either planning to attempt another crowdfunding project or currently in negotiations with a publisher or investors. They apparently attended E3 last summer. Let’s hold out hope this game gets released someday but seems very doubtful it will be in the near future.
