Good question. 2 previous deadlines resulted in a tragic build with missing content and a lot of bugs. I decided to change a workflow and instead of having a specific date of release, I have a list of goals I want to achieve before release.
I guess the roadmap approach of checking the milestones of the project is better than a strict time and date. My dream scenario is to finish the vanila version of Debtors (without Debtors: Adventures) till the end of 2023.
I have new, naughty projects in mind but I need to close this one first ;]
