1. Girls cannot be added at this moment. You can generate a random male/female and the protagonists on the PlayRoom mode.
2. Pregnancy will be part of the game, but it's not on my plans to add it in short term.
3. If a pregnancy system its included it's a good idea.
4. The game is not really demanding on system requeriments, I develop it on a old PC and I get 60 fps with max graphics. I sugest you to try it.
5. C:\Users\[YourUser]\AppData\LocalLow\TheArkCompany\The Ark.
6. There is a Discord but only avaliable to patreons.
