Afaik any kind of school-content is a hard NO from Steam. They would be concerned that Marc, Catherine, etc, might be interpreted as being underaged. On the other hand, the Prometheus-stuff shouldn't be a problem for Steam, and they aren't bothered by incest either.I've been asked a few times that, but Project Myriam is way too experimental for it I think, but maybe I could do it for the next one, will see.
