Steam Version: Has no Shota content, so the urchins questline is not available. In exchange, they created a Steam exclusive Questline where Claire buys a house and encounters many tenants.No, the difference between the versions (f95 and steam) and how's the development going, and if there is a discord server.
Patreon Version: Doesn't have the Landlady quests, but does contain the urchins quest line (also not very well developed, yet).
Complete Version (the one you get here): Has ALL the content.
