The main difference between the Free, Bull, Cuck's End and The Dom Edition is the amount of content .
The Community Free Edition - Is just the main story, it only have Angelica's content,
The Bull Edition it will have additional content with Mark only, if you played the game already you'll see that it's only the intro but it have a lot of content.
The Cuck's End which complements the Bull's Edition, Will be telling the additional story of Mark and Henry and their past together and many other thing on the updates to come.
As for the Dom Edition it will be a way more complete story, telling the story of all the 4 protagonist, those being Angelica, Aria, Mark and Henry, so the Dom Edition is the most complete because it contains the point of view and story of the 4 of them. The additional content is not limited to just a couple of renders, it has story content that is significant enough
With the exception of the Free Community Edition All the other 3 are patreon only, released in the community this time as an exception
So,if i understand right,"The game is The community free edition" and the others 3 editions (Bull,Cuck's End and Dom) are just short storyline about Angelica's storyline from her past,but the one who will be updated in future is the Community Free Edition - Is that right?
