Breeding Season wasn't abandoned, this game was destroyed by this selfish jerk, who's now draws for Cloud Meadow.
Not quite. The original creator had issues keeping to his own squedules and teaming up with an artist led him to priorising redesigning and pushing off his own work to others. At the point the artist jumped ship the remaining members of the team were also about to leave, because the OC didn't even reliably appear to his own streams anymore and the team was filling in to cover for him.
All of them left statements at the time.
To be clear I don't blame any single person for what happened. But then we get into the "if A only had ..." territory and that doesn't help anyone.
As for the "selfish jerk", he didn't destroy the project, nor was he selfish. He saw that the OC milked the project for all it was worth without doing any of the work, and wanted to stop him exploiting his fanbase. If OC had chosen to do so, he could have returned to his own art as that was the only part being owned by the artist.
That's my opinion based on the statements and evidence posted by all parties at the time, including e-mails bedween the OC and the artist. Feel free to disagree.
TLDR: Don't hate on people for mismanaging projects with feature creep. These game are prone to it.
