I wonder how I can best account for this in the system...
> Released, but content still planned
Silksong is like this, there are other games where they release patches for years?
Is done no longer supported? I ask because take any paradox grand strategy game, if I understand your rubric, they're done only if they are no longer the supported mainline game, IE Crusader Kings 2 is done, as 3 is where all the support is going?
Obviously this is imperfect because look at the witcher 3, after more than a decade they announced a new DLC (Which is a tie in to the new game but still)
Basically is this a done experience that I can have, if I'm summarising you correctly
But if this is your rubric, and you find an audience that finds value from this rubric, I don't mean to denigrate your work here!
I think if you have to keep adding these caveats to some of the most popular games of the past decade, then something about your classification criteria is fundamentally broken.
