At the moment, the collection is a work in progress. Only three games are available but many more will be added in the future.
The collection will be considered completed when it has its 40 games released on all platforms. Due to the fact that I am working alone, I cannot give an estimate for the release date of the future games, but I am already close to finish "Hounds & Jackals", the fourth title and "Puluc", the fifth, is well underway
The production has slowed down after the release of XII Scripta because I have decided to rework everything to streamline the way I work (in order to be more efficient in the future) and remake the interface and most systems from scratch for a better experience.
From now on, games should be released much more faster! You can see the roadmap here.
